On Solaris 9, "nohup -p pid ..." arranges for the referenced processes
to become immune to hangups.

Similiarly, "nohup -g pgid ..." arranges for the referenced process
groups to become immune to hangups.

There are two other related options:

-F "force".  Grab control of the target process, even if another
   process already has control.

-a "always".  Change the disposition of SIGHUP and SIGQUIT even if the
   process has installed a handler for either signal.

I don't know why someone would want these options.
Perhaps JGraham can explain why they'd be useful.
