If this method is made synchronous, we need to ensure that people dont try to use it from external threads. At the very least, a warning against that should be added to the docstring. The event.set() call should raise a clear enough error but I feel that the event loop thread id member set should be moved to after the event set, to be safe.

This should avoid breakage when called from external threads.
Suggested change
