 Module Name:	src
 Committed By:	christos

 	src/sys/sys: param.h proc.h uidinfo.h
 Log Message:
 PR/53998: Joel Bertrand:  Limit the number of semaphores on a
 per-user basis not a per-process.  We cannot really keep track on
 a per-process basis because a parent process can create the semaphore
 and a child can free it taking credit for it.  There is also a
 similar issue about resource exhaustion if we limited the number
 of lwps per process as opposed to per user (which we don't).
