 arma suggested I write a proposal for this, but I believe it is a flat out
 bug. When a relay goes down, it looses its 24 hour observed bandwidth
 window. For fast relays, this can be catastropic, as it takes weeks for
 them to regain their bandwidth due to our slow descriptor refresh
 interval. The slow descriptor refresh interval can be shortened, but that
 requires careful study to make sure we do not increase the descriptor load
 on clients.

 If we just instead stored this info in the state file to survive crashes,
 high bandwidth relays would still spend a *loooong* time gathering
 bandwidth (and maybe this is a really good thing?), but will at least not
 have to restart when they die.
