-The GNU mmalloc (mapped-malloc) package.	fnf@cygnus.com
-
-
-Description
------------
-
-This is a heavily modified version of GNU malloc which has been extended to
-use mmap() as the basic mechanism for for obtaining memory from the system,
-rather than sbrk().  This gives it several advantages over the
-more traditional malloc:
-
-    *	Providing suitable precautions are taken to avoid memory region
-	collisions, sbrk() is now available for use by applications that
-	use this package and still need to use some memory management
-	package that includes functions like malloc/realloc/free.
-
-    *	Several different memory pools can be used, each of them growing
-	or shinking under control of mmap(), with the mmalloc functions
-	using a specific pool on a call by call basis.
-
-    *   By using mmap, it is easy to create data pools which are intended to
-	be persistent and exist as a filesystem object after the creating
-	process has gone away.
-
-    *	Because multiple memory pools can be managed, data used for a 
-	specific purpose can be allocated into it's own memory pool, making
-	it easier to allow applications to "dump" and "restore" initialized
-	malloc-managed memory regions.  I.E., the "unexec" hack popularized
-	by GNU emacs could potentially go away.
-
-
-Implementation
---------------
-
-The mmalloc functions contain no internal static state.  All of mmalloc
-internal data is allocated in the mapped in region, along with the user
-data that it manages.  This allows it to manage multiple such regions
-and to "pick up where it left off" when such regions are later dynamically
-mapped back in.
-
-In some sense, malloc has been "purified" to contain no internal state
-information and generalized to use multiple memory regions rather than a
-single region managed by sbrk().  However the new routines now need an
-extra parameter which informs malloc which memory region it is dealing
-with (along with other information).
-
-For ease of initial implementation, and to avoid exporting or importing
-any more global variables or routines than necessary, this package is
-implemented with all functions contained within a single source file.
-At some future point, once everything has stabilized, it may be desirable
-split it up into separate files.
-
-The functions initially provided by mmalloc are:
-
-    void *mmalloc_attach (int fd, void *baseaddr);
-    void *mmalloc_detach (void *md);
-    int mmalloc_errno (void *md);
-    int mmalloc_setkey (void *md, int keynum, void *key);
-    void *mmalloc_getkey (void *md, int keynum);
-
-    void *mmalloc (void *md, size_t size);
-    void *mrealloc (void *md, void *ptr, size_t size);
-    void *mvalloc (void *md, size_t size);
-    void mfree (void *md, void *ptr);
-
-Backwards Compatibility
------------------------
-
-To allow a single malloc package to be used in a given application, provision
-is made for the traditional malloc/realloc/free functions to be implemented
-as special cases of the mmalloc functions.  In particular, if any of the
-functions that expect malloc descriptors are called with a NULL pointer rather
-than a valid malloc descriptor, then they default to using an mmap'd region
-starting at the current sbrk() value and mapped to /dev/zero.  Applications
-can simply include the following defines to use the mmalloc versions:
-
-	#define malloc(size)		mmalloc ((void *)0, (size))
-	#define realloc(ptr,size)	mrealloc ((void *)0, (ptr), (size));
-	#define free(ptr)		mfree ((void *)0, (ptr))
-
-or replace the existing malloc/realloc/free calls with the above patterns
-if the #define's cause problems.
-
-Note that this does not prevent calls to malloc/realloc/free within 
-libraries from continuing to use the library version of malloc, so if this
-is a problem, the compatibility issue needs to be dealt with in another way.
-
-
-Function Descriptions
----------------------
-
-    void *mmalloc_attach (int fd, void *baseaddr);
-
-	Initialize access to a mmalloc managed region.
-
-	If FD is a valid file descriptor for an open file then data for the
-	mmalloc managed region is mapped to that file, otherwise "/dev/zero"
-	is used and the data will not exist in any filesystem object.
-
-	If the open file corresponding to FD is from a previous use of
-	mmalloc and passes some basic sanity checks to ensure that it is
-	compatible with the current mmalloc package, then it's data is
-	mapped in and is immediately accessible at the same addresses in
-	the current process as the process that created the file.
-
-	If BASEADDR is not NULL, the mapping is established starting at the
-	specified address in the process address space.  If BASEADDR is NULL,
-	the mmalloc package chooses a suitable address at which to start the
-	mapped region, which will be the value of the previous mapping if
-	opening an existing file which was previously built by mmalloc, or
-	for new files will be a value chosen by mmap.
-
-	Specifying BASEADDR provides more control over where the regions
-	start and how big they can be before bumping into existing mapped
-	regions or future mapped regions.
-
-	On success, returns a "malloc descriptor" which is used in subsequent
-	calls to other mmalloc package functions.  It is explicitly "void *"
-	("char *" for systems that don't fully support void) so that users
-	of the package don't have to worry about the actual implementation
-	details.
-
-	On failure returns NULL.
-
-    void *mmalloc_detach (void *md);
-
-	Terminate access to a mmalloc managed region by closing the base
-	file and unmapping all memory pages associated with the region.
-
-	Returns NULL on success.
-
-	Returns the malloc descriptor on failure, which can subsequently
-	be used for further action (such as obtaining more information about
-	the nature of the failure).
-
-    void *mmalloc (void *md, size_t size);
-
-	Given an mmalloc descriptor MD, allocate additional memory of
-	SIZE bytes in the associated mapped region.
-
-    void *mrealloc (void *md, void *ptr, size_t size);
-
-	Given an mmalloc descriptor MD and a pointer to memory previously
-	allocated by mmalloc in PTR, reallocate the memory to be SIZE bytes
-	long, possibly moving the existing contents of memory if necessary.
-	
-    void *mvalloc (void *md, size_t size);
-
-	Like mmalloc but the resulting memory is aligned on a page boundary.
-
-    void mfree (void *md, void *ptr);
-
-	Given an mmalloc descriptor MD and a pointer to memory previously
-	allocated by mmalloc in PTR, free the previously allocated memory.
-
-    int mmalloc_errno (void *md);
-
-	Given a mmalloc descriptor, if the last mmalloc operation
-	failed for some reason due to a system call failure, then
-	returns the associated errno.  Returns 0 otherwise.

-Z0.  Access data structures with accessor macros, then turn the heapinfo
-Zinto several arrays for faster access on machines with addressing modes.
-ZAlso, this eventually raises the possibility of maintaining multiple
-Zheaps.
-Z1.  Possible heuristic to catch multiple frees.  Introduce an extra word
-Zof heapinfo that says whether the remaining info is for something
-Zbusy or something free.  Then we can catch attempts to free already-free
-Zlarge blocks, as well as things not belonging to malloc at all.  In the
-Zcase of a fragment, we can check if the fragment looks like it *already*
-Zbelongs to the fragment list, by comparing it with the "first" fragment
-Zof the block, or checking its "prev" pointer to see if it points into
-Zthe block.  Then if it looks like it might we can exhaustively search
-Zthe block's free list to see if the fragment is there or not.  Extending
-Zthe heapinfo structure would have the benefit of making it a power of
-Ztwo and thus making array indexing faster, perhaps.  Suitably adapted,
-Zthis heuristic could also catch invalid pointers passed to realloc.
-Z
-ZAll of these additional features require the inclusion of <malloc.h>.
-Z3.  indirect reference allocator: ialloc(), ifree(), irealloc().
-Z4.  garbage collecting allocator: galloc(), garbage(), gfree(), grealloc().
