Re: DEAN@USC-ECL's problem -- it's due to a "feature" of the C shell.

While your program is running, the tty's pgrp is assigned to the child
process created by csh.  When it terminates, csh regains control of the
tty.  HUP signals are sent only to the group that controls the tty; thus,
your orphan process never receives it.  Ain't progress wonderful....
