Commit Message

Fix corner case with joining processes/queues (#1473)

If a process places items in a queue and the process is joined before the queue is emptied, it can lead to a deadlock under some circumstances. Closes AIRFLOW-61.

See for example: https://docs.python.org/3/library/multiprocessing.html#all-start-methods ("Joining processes that use queues")
