Is there any chance that POSIX semaphores will be anything other than
experimental in the future, or is there no interest?  Further, the man
page indicates that the FreeBSD, POSIX semaphore implementation is not
capable of supporting multiple process semaphores.  I saw a similar note
on a Linux man page.  I think this is a shame, since POSIX semaphores seem
to be well designed (from a user point of view) compared to SYSV
semaphores, which are a total mess.
