Comment (by nickm):

 I think this code looks okay but before we merge it, I think we should
 have a patch for tor-spec that explains the new behavior of the replay
 cache.  We should also have a quick proposal that explains why it's safe
 to allow replays, since I've usually thought of them as a way to mount
 active traffic analysis attacks.
