The fact that we don't fail attempts to use pshared outright is probably dubious. They cannot possibly work as currently implemented aside from fork() since the structure embeds a file descriptor and file descriptor indices are a per-process namespace, not a global namespace.
FWIW, this is what confused me. It tends to be kind of a land-mine, since programs can be ported from Linux, and appear to work at first for casual use. If we don't support pshared, we should return an error from sem_init() to make it obvious. Also, perhaps the sem_init() man page should mention sem_open(), since that seems to be the only way to really share a semaphore between processes on FreeBSD.
