Argh...
OK, let's put it this way. Come up with a program that does soemthing useful
and doesn't do any IPC at all. About the only thing I can think off is one
that runs ONLY under the CLI, has no diagnostic messages, and toggles the 7kHz
filter on and off (or does some other trivial hardware hackery (or hijackery)).
IPC is integral to the Amiga. Sharing memory between a bunch of tasks is not
something you can get away from. It's rare on UNIX.
Maybe I need a disclaimer: "If this message uses different magic incantations
than the ones you're used to, try to see if that effects the content before
flaming"?
