Right at the moment, the backend will exit with status 0.  I think you
are thinking the same thing I am: maybe a backend that receives SIGTERM
ought to exit with nonzero status.

That would mean that killing an individual backend would instantly
translate into an installation-wide restart.  I am not sure whether
that's a good idea.  Perhaps this cure is worse than the disease.
Comments anyone?
