[New-bugs-announce] [issue33562] Check that the global settings for asyncio are not changed by tests

[Brett Cannon]

New submission from Brett Cannon <brett at python.org>:

There were not checks in test.libregrtest.save_env to make sure tests were not mucking with the default event loop. The settings to check seem to be:

'asyncio.get_event_loop_policy', 'asyncio.get_event_loop',
'asyncio_get_exception_handler', 'asyncio_get_debug',
'asyncio_get_child_watcher',

I have a PR that I'm working on that checks these things and it looks like the following tests are being a little sloppy:

test_asyncgen
test_contextlib_async
test_coroutines
test_socket
test_sys_settrace

And test_asyncio never seems to complete.
