More likely, its parent is now init, but its parent used to be the
shell.  That is, when it was started, it forked and exited to put
itself into the background.

Huh?  As far as I can tell, my processes never get HUPs when the shell
exits.  Certainly not if they're running.  (If they are stopped, the
shell warns, but if you insist, it will go ahead and exit.  It then
does send some signal to the stopped jobs, but I don't recall what
signal.  But none of that happens to running jobs.)
