No shared memory, no semaphores - (currently) true.

No IPC, no messages - go forth and read:

	SOCKET(2)
	BIND(2)
	LISTEN(2)
	ACCEPT(2)
	CONNECT(2)
	SEND(2)
	RECV(2)

in your 4.2BSD manuals, then try again.  (Unlike those in a certain famous
USDL-developed system, they work over a network.  Wait a minnit, somebody's
saying they don't work over a network because nothing other than file
transfer and remote command execution works over a network in that system.
Gee.... No!)

No locks - no record locks, but for file locks, go forth and read:

	FLOCK(2)

and try again.

Moral: flaming about the general unworthiness of some UNIX system other than
your favorite generally causes singed eyebrows and little illumination.
(This goes for you Berkeleyphiles - and even Researchphiles - out there,
too.)
