				IPC is only necessary when the
	creator of the processes did not expect them to communicate, as in
	processes belonging to different users.
----------
Surely you don't mean the first part of that sentence as written. A process
isn't going to be much good with ANY kind of IPC method if it wasn't
intended to use it. The need for IPC is to allow communication between
processes operating independently, whether for the same or different
creators, but the use of the communication medium must be thought out
carefully in advance in any case. Each process must know exactly what
kind of communication is to be expected and how to respond to it.
