Correct, it doesn't do that prior to the patch. It looks like it's never
exiting this loop:
try:
for worker in workers:
worker.join()
except:
either when a Ctrl+C happens, or when all the processes finish. I guess
it's stuck in there for some reason. So even the test runner doesn't
finish. Still investigating.
Also to answer Greg's question, yes we were using dosep before. The
problem seems to be related to swtiching from multiprocess.Pool to doing
the pumping manually.
