This is an interesting idea. It's not a replacement for periodic probing,
because there's no guarantee the crashed server will come back in a timely
manner, if at all. But, crash reporting could speed up the resync process.
I think this could already be done today by keeping a list of presences you
have sent out, and upon restart just connect to all of the servers and send
unavailable presences. There's probably major optimization potential here
