But Doctor, it hurts! ;-)

It's simplest to think of starting and stopping the frontend
and backend at the same time but each is subject to dying,
being killed, a machine is rebooted or crashes, etc. Either
end should be well behaved even if the other is not. Currently,
the Live TV recording does successfully exist if the frontend
goes away ever since Isaac patched this last week.

The opposite should also work. If the backend is restarted,
the frontend should notice and reconnect without needing to
be restarted. I suspect that this will be fixed, or will be
easier to fix, after the multiple backend code is in place.
I assume the frontends will need to check to be sure they have
a connection before making requests to a backend.

I'd hate to think that we'd need to stop and start every
frontend and backend on every machine each time one
process dies.
