Reopening to rerun the test in case master changed

[robertwb]

Thanks. I thought all tests were passing before, I'll look into the failure here. (I do see a lot of

>   self._maybe_sample_exception(exc_info, windowed_value)
E   TypeError: Argument 'exn' has incorrect type (expected BaseException, got tuple)

which is a bit odd.)

those should be fixed now, @damccorm addressed those this week
