Comment (by andrea):

 Replying to [comment:4 nickm]:
 > I have an implementation in "bug9683_testing_024". It won't be faster
 yet, since it runs the old algorithm and the new cleverer one, and
 compares the results to make sure they match.  Can somebody try it out on
 a relay, and see whether you get a bunch of BUG messages?

 Code review looks okay; I'll give it a bit of testing time on a relay.
