[lug] linux process supervision

[Atkinson, Chip]

Yes indeed it does.  Bash doesn't have the restriction, but Ksh, at least on
HPUX 10.20 does require that nohup be used to run a process if you wish to
log out and have it still run.   Once the process dies, it does _not_ get
restarted automatically when run with nohup.
