Description
I was doing some debugging of the tests trying to figure out why a CREATE event was delivered even though a file should have existed before the watch. My debugging uncovered a deadlock in watch when a sleep_ms is performed before it. Something about the CFRunLoop code I imagine but I couldn't track it down.
This causes the deadlock:
