async related issues on Windows 11

A recent update to Windows 11 is causing abnormalities in the test suite.  Note that the tests are not *failing*, but they are emitting error messages.

I believe the offending Windows update is [KB5012592](https://support.microsoft.com/en-us/help/5012592).

```
python -m test test_contextlib_async test_coroutines test_unittest test_asyncio
