Yes I meant SIGTERM not SIGHUP.

That is basically what my modification does.  The delay really just
sends SIGKILL to the supervised process after the delay and waits for it
to die. The delay just gives the supervised process time to gracefully
shutdown before trying to more aggressively kill it.

That is my opinion, but it isn't the current behavior so I figured
others might have a different opinion.
