So do at least some modern UNIXes (SunOS 4.x, System V Release 4,
OSF/1, probably others).

Amen.

Of course, UNIX isn't exactly lacking in them these days, either. 
Consider a "typical" UNIX system with the Usual Collection of S5 and BSD
stuff; it probably has:

	FIFOs (I'd call them "named pipes", but I don't want to confuse
	the OS/2oids in the audience)

	S5 message queues

	S5 shared memory

	sockets of various flavors

and, if you're *really* lucky, you may also have various streams-based
IPC mechanisms as well.  There may well be some that I've forgotten....
