When a switchboard connection dies (at the TCP level) and there are still
queued messages, they will now be moved back to the main queue and a new
sb will be created to try to send the messages again. I hope this will
solve some/most/all of the "Closing switchboard with unsent messages"
problems, but can't be sure since this problem isn't very easy to reproduce.
At least it should solve the ones caused by keeping spare switchboards
around. Also enabling switchboard debugging output if configured with
--debug=1, at least for now this will be useful.
