Comment (by arma):

 Ok, this ticket came a long way since I last noticed it.

 I agree with what Yawning said way up at the top -- this is best fixed
 inside Tor.

 Tor already has the mechanism for figuring out which bridges work, and
 also the mechanism for keeping state about which one it picked to be its
 "first" bridge (they go into the state file and are treated just like
 guards).

 So all Tor needs to do is shuffle its bridge list every time it reads it
 from torrc, and I think everything else we need will follow.

 (Except the bandwidth weighting stuff -- either Tor chooses from all of
 them equally because it doesn't have any descriptors at the time it
 chooses which one will go into the state file first, or it does have the
 descriptors so it weights by the self-advertised bandwidths in the
 descriptors. I'd have to check, but my guess would be the former. Still, I
 think that is better solved inside Tor, where Tor Browser's job would be
 to add a weight to the bridge line.)
