[issue44036] asyncio SSL server can be DOSed, event loop gets blocked: busy loops and uses 100% CPU

New submission from ghost43 : This is about a potential DOS vector that can get an asyncio server serving SSL connections to enter a busy loop and hang. To recover the server (python process) needs to be restarted. See downstream report at https://github.com/spesmilo/electrumx/issues/92
