Comment(by arma):

 Replying to [comment:9 arma]:
 > D) I expect that when it reaches 100 build times, it will produce an
 atrocious cbt. We should think about how to cap the number at something
 realistic. I am guessing that these Pandoras are simply never planning to
 answer me, no matter my timeout.

 How about capping it at twice the maximum circuit build time ever
 witnessed? That should let it grow plenty high while still preventing it
 from reaching the "2 million seconds" that I got yesterday.

 More generally, I fear the algorithm for computing the right timeout
 behaves poorly in the face of even a small fraction of failing relays.
