summary:

bpo-40782: Change asyncio.AbstractEventLoop.run_in_executor to be a method not a coroutine (GH-21852)



asyncio.AbstractEventLoop.run_in_executor should be a method that returns an asyncio Future, not an async method.
This matches the concrete implementations, and the documentation better.
