      The default `asyncio` event loop policy only automatically creates
      event loops in the main threads. Other threads must create event
      loops explicitly or `asyncio.get_event_loop` (and therefore
      `.IOLoop.current`) will fail. Installing this policy allows event
      loops to be created automatically on any thread, matching the
      behavior of Tornado versions prior to 5.0 (or 5.0 on Python 2).
