Comment (by arma):

 I also just added {{{cbtmintimeout=5000}}} to moria1's consensus params,
 on the theory that if clients really were learning super low timeouts and
 they weren't unlearning them, then we'll make them more likely to be
 willing to use the circuits they make.

 This choice is not uniformly a win, since with this raised min, clients
 that had computed a super-fast cbt will now be less likely to abandon it
 (and move back to the slow learning phase, during which they use a timeout
 of 60s). But it could help us in the hypothesis 2 case, where due to bugs
 or luck clients are sticking to their super-fast cbt despite 80% circuit
 failure.
