The bug you notice existed before that merge too.  Jonathan helped me
diagnose it: see http://twistedmatrix.com/bugs/issue1294.  It appears trial
is calling reactor.iterate(0) during cleanup, and not expecting that it
could raise an exception.  Making iocp's doIteration swallow and log that
error, like the other reactors do, will probably fix this.  Making trial
deal with that error better (as apparently is not too hard to do with one of
the trial branches) would also fix it.
