Comment(by arma):

 Replying to [ticket:5048 nickm]:
 > Wanoskarnet in #tor suggests that the INT32_MAX maximum for
 cbtmintimeout is ridiculously high.  If it were ever set to an absurdly
 high value, then all users who had LearnCircuitBuildTimeout set would
 break much of the time, while users with LearnCircuitBuildTimeout turned
 off would break only some of the time.

 Let me see if I can get my logic straight here. If we set an absurdly high
 minimum, say, 200 seconds, then that means every client that computes a
 cbt for itself would never compute one less than 200 seconds. Most would
 probably pick 200 seconds.

 So that means these clients would only give up on a circuit ("it's taking
 too long") if it took 200 seconds to build.

 How would that cause them to break much of the time? I mean, it wouldn't
 be great, but I don't think it's as bad as you say.
