 Replying to [comment:1 arma]:
 > Woah. Yeah. So, right now we close circuits 60 seconds after making
 them, even if we opt to make testing circuits much less frequently? That
 is, when we have any predicted ports, we're going to end up churning
 through all our circuits every minute, anyway? That's crummy. It seems
 like the idle-timeout-while-learning should be a function of the
 cbttestfreq?

 Yes, I think we need to make it configurable, and possibly backport the
 change.
 (But not to 0.2.8, because it's not supported as of 1 January 2018.)

 I'm not sure what to do about the regular connection timeout. We should
 check what it was before, and maybe see if it needs to be longer.
