Hi. I have a high cpu usage using asyncio streams/sockets with connection pool (I tried on cpython 3.8-3.9 on mac and debian). Seems some noop handler is continously called polling ports in selectors.
Here is a simple example to reproduce https://github.com/romikforest/asyncio_streams_high_cpu_usage2

Thank you a lot if you can take a look.
