Right now, Async IO module is not automatically creating a new event loop on threads that are not the main thread (https://github.com/python/cpython/blob/master/Lib/asyncio/events.py#L638), but it should be interesting to do it. For example, WSGI applications handle web requests by spawning a new thread. If we allow Async IO module to create event loops on those threads, we will improve its adoption for developing web applications.
