Is there some programming pattern that would enable me to detect when an asyncio event loop becomes idle in the following sense? Say that my execution path branches in some complex way, say, using asyncio.gather(), but I know that each branch eventually awaits some idle coroutine, such as a socket or a subprocess. Say I know these coroutines actually never yield, so the event loop will execute whatever python code it can but eventually will just wait for those idle coroutines. Is there a programmatic way to detect such a state and stop the loop?
