asyncio.Event.wait() doesn't seem to be cancelled by asyncio.wait_for(). Ctrl-c in the attached example produces output below. I'm not certain the code is correct though the documentation for wait_for() suggests it should work. Without the wait_for() it doesn't suffer from pending task destruction. This is Python 3.4.3.
