The docs of SelectorEventLoop and ProactorEventLoop contain examples that call asyncio.set_event_loop:

      selector = selectors.SelectSelector()
      loop = asyncio.SelectorEventLoop(selector)

But this won't have any effect on code that uses, because creates a fresh event loop. Since is the recommended way to execute async code and is used consistently throughout the documentation, this might be confusing to someone who tries to e.g. use the proactor loop on Windows.

I propose the following:

* add a disclaimer that instantiating the event loop won't affect calls to, and that loop.run_until_complete() must be used; and

* link to asyncio.set_event_loop_policy(), which does work with, but doesn't allow fine-tuning the details, such as which selector to use for the SelectorEventLoop.
