[New-bugs-announce] [issue42838] Wait for cleanup coroutines before event loop is closed.

[xloem]

New submission from xloem <0xloem at gmail.com>:

To handle destruction of resources especially during exceptions, it would be nice if there were some way to provide coroutines/tasks that run at the termination or closure of an event loop.  There are a lot of api options here.  Maybe a simple one would be to have close() call a run_until_closed() function that starts all of these and steps the loop to wait for them, before closing, and provide run_close() functions to queue them for delay.
