-
- Locking is loosely controlled by the preprocessor variable

- -- 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?... */
