+<H2>Black-listing</h2>

+The collector implements <I>black-listing</i> of pages, as described

+Boehm, ``Space Efficient Conservative Collection'', PLDI '93</a>, also available
+<A HREF="papers/pldi93.ps.Z">here</a>.
+<P>
+During the mark phase, the collector tracks ``near misses'', i.e. attempts
+to follow a ``pointer'' to just outside the garbage-collected heap, or
+to a currently unallocated page inside the heap.  Pages that have been
+the targets of such near misses are likely to be the targets of
+misidentified ``pointers'' in the future.  To minimize the future
+damage caused by such misidentifications they will be allocated only to
+small pointerfree objects. 
+<P>
+The collector understands two different kinds of black-listing.  A
+page may be black listed for interior pointer references
+(<TT>GC_add_to_black_list_stack</tt>), if it was the target of a near
+miss from a location that requires interior pointer recognition,
+<I>e.g.</i> the stack, or the heap if <TT>GC_all_interior_pointers</tt>
+is set.  In this case, we also avoid allocating large blocks that include
+this page.
+<P>
+If the near miss came from a source that did not require interior
+pointer recognition, it is black-listed with
+<TT>GC_add_to_black_list_normal</tt>.
+A page black-listed in this way may appear inside a large object,
+so long as it is not the first page of a large object.
+<P>
+The <TT>GC_allochblk</tt> routine respects black-listing when assigning
+a block to a particular object kind and size.  It occasionally
+drops (i.e. allocates and forgets) blocks that are completely black-listed
+in order to avoid excessively long large block free lists containing
+only unusable blocks.  This would otherwise become an issue
+if there is low demand for small pointerfree objects.

 <H2>Thread support</h2>

 the only reasonably well standardized thread model, supports too narrow
 an interface for conservative garbage collection.  There appears to be
