RE: multiprocess:

Have a look at how the truss code in acid handles the hang bit
and I think you'll find it's not too hard to do what you want.  Truss
deliberately avoids doing what you're asking because otherwise
programs like rc, mk, etc. are a true pain to truss.

To see how acid handles multiple process, see /sys/lib/acid/thread.
It's really not hard.
