Hum, sometimes it's better to wait for AppVeyor :-) You broke all Windows 
buildbots! :-) Example:

[issue32296] Implement asyncio._get_running_loop() and get_event_loop() in C

2017-12-12 Thread Yury Selivanov 

New submission from Yury Selivanov :

asyncio.get_event_loop(), and, subsequently asyncio._get_running_loop() are one 
of the most frequently executed functions in asyncio.  They also can't be sped 
up by third-party event loops like uvloop.

When implemented in C they become 4x faster.
