Nope.  It does its best to clean up stuff that it knows is "in" the reactor 
(sockets, timers, and the like), but since threads can kind of do ~whatever~ 
there hasn't been support for that.

deferToThread is a bit of a special case and you make a good point here: there 
should probably be special support for it in trial.

That can definitely happen.  For the time being you probably want to add your 
own deferToThread layer and have a testCase.addCleanup that makes sure all the 
relevant Deferreds have fired.
