test_asyncio needs your love

Hi,

As a member of the Night's Watch, I'm fixing the CI in the darkness
for you (*). Last weeks, I managed to fix most issues. But I decided
to give up on test_asyncio failures. I no longer have the bandwidth to
investigate these complex issues.

(*) https://pythondev.readthedocs.io/ci.html

I need your help to debug and fix the following test_asyncio issues.

(1) "test_asyncio altered the execution environment" open for almost one year
https://bugs.python.org/issue38912

(2) "asyncio: MultiLoopWatcher has a race condition (test_asyncio:
test_close_kill_running() hangs on AMD64 RHEL7 Refleaks 3.x)" open for
longer than one year
https://bugs.python.org/issue38323

There are 8 more open issues which contain "test_asyncio" in their
title, but these 2 are the ones causing most troubles on the CI.

Victor

Thanks, Justin! I'll look over your PR, try to replicate the failure
locally, and test it against the patch to see if it still occurs. I think
your analysis of the issue makes sense, with it likely being a race
condition between the test prototype "MyProto" and the event loop.
