Stopping and restarting a proactor event loop on windows can lead to spurious errors logged (ConnectionResetError while reading from the self pipe). This fixes the issue by ensuring that we don't attempt to start multiple copies of the self-pipe reading loop.

LGTM. Ben, should this be backported to 3.8/3.9? |

Yes, this should be backported to 3.8/3.9. I haven't tested with those branches but the bug is definitely present in 3.8 (the bug is probably older but it was revealed when the proactor event loops became the default in 3.8) and I don't see any changes since then in the relevant parts of the code. |

@1st1: Please replace |

Simply closing the event loop isn't enough to avoid warnings. If we don't also shut down the event loop's default executor, it sometimes logs a "dangling thread" warning. Follow-up to pythonGH-22017
