Subject: a limited port of sys V shared memory available soon

Hi,
	system V shared memory was needed for some work I was doing and I
know many people are interested in this as well.  I will be posting a port
with limited functionality to the list tomorrow but be warned, it is
_very_ limited.  Here are the problems/shortcomings I can think of (off of
the top of my head):

shmat must be called after a fork()
shmat must be called by a forked process/thread (I think)
shmget mostly ignores permissions
shmctl is mostly useless, ditto for shmdt

I know this is very limited.  I wrote it only to meet my needs and those
needs are to share memory among fork()'ed processes.  Perhaps someone else
can take it and advance it further.
