Erm... not really.  You responded to a semctl() man page quote on IPC_RMID
with saying that FreeBSD does something else, but you didn't mention you
were talking about talking about shmctl.  Everyone who is seeing that
IPC_RMID doesn't happen until the last reference is released is talking
about shmctl, while everyone saying it happens right away is talking about

shmctl and semctl manipulate two different things.  I'm not sure what you
are suggesting to use shmctl for since we are dealing with semaphores not
shared memory...
