I think this is fairly irrelevant, because a not-yet-backend should
have a fairly short timeout (a few seconds) before just shutting
down anyway, so that malfunctioning clients can't cause denial of
service; the particular case you mention is just one scenario.

I have been intending to implement this soon if Peter didn't.

OTOH, it'd be easy enough to turn on SIGTERM/SIGQUIT too, if you
think there's really any value in it.
