-/** Locking 
-
-   Locking is loosely controlled by the preprocessor variable
-   BFD_LOCKS.  I say loosely because Unix barely understands locking
-   -- at least in BSD it doesn't affect programs which don't
-   explicitly use it!  That is to say it's practically useless, though
-   if everyone uses this library you'll be OK.
-
-   From among the many and varied lock facilities available, (none of
-   which, of course, knows about any other) we use the fcntl locks,
-   because they're Posix.
-
-   The reason that @code{bfd_openr} and @code{bfd_fdopenr} exist, yet
-   only @code{bfd_openw} exists is because of locking.  When we do
-   output, we lock the filename file for output, then open a temporary
-   file which does not actually get its correct filename until closing
-   time.  This is safest, but requires the asymmetry in read and write
-   entry points.
-
-   Perhaps, since unix has so many different kinds of locking anyway,
-   we should use the emacs lock scheme?... */
