 (About to rebase my work onto that.)

 Ok, just finished a test run on `master`
 ([[https://gitweb.torproject.org/stem.git/commit/?id=ed6460df4a6fa8446a1e2923bddde652f5d91ed7|ed6460df4a6fa8446a1e2923bddde652f5d91ed7]]).

 Based on the output (still failing) and past experience prior to this
 change, I'm going to reopen this ticket - something in these commits seems
 to be causing this.

 atagar, if you think it's something specific to my configuration / setup,
 let's discuss over IRC to nail this down.

 Ran:
 `tox -- -a`
 (which is basically `run_tests.py -a` on py27 and p35

 Here's snippet output...

 So, seemingly: seeing multiple threads lingering, independent of test
 failure.
