test_asyncio is quite big. Can you run test_asyncio in verbose mode, and attach the output as a file to the issue? Or try to identify a few examples of tests which fail with "The handle is invalid" errors"?

It seems like "The handle is invalid" errors" error occurs while calling _cancel_overlapped().
