You *could* use twisted.runner for process control even if you
don't use twisted for your networking code. It does seem like
a funny thing to do, but there's nothing stopping you from doing
that. The example code in twisted.runner starts up a few shell
scripts that die on their own accord, and make sure they get
restarted, so it doesn't rely on twisted being used in the
processes it controls.
