Comment (by robgjansen):

 After numerous big fixes and new Tor network model, I finally have some
 initial results. I tested nickm/kist at commit
 55814effcb96ff4998e75a2136ac2ed631247d8a with `UseKIST 0` and `UseKIST 1`.

 The results totally blow. Downloads times increased dramatically when
 using the new feature and Tor queue times were unchanged. I also noticed
 download failure modes around 5 minutes and 10 minutes, and am still
 looking into the cause.

 None of this makes sense to me yet, and I have little confidence in the
 results I got. (Specifically, the queue times should have at least
 slightly changed, but I have not observed that.) My current thinking is
 that the problems are primarily due to the changes that occurred as a
 result of using a new network model. So my next step is to simulate under
 our older, stable model and go from there.
