[issue22448] call_at/call_later with Timer cancellation can result in (practically) unbounded memory usage.

[Guido van Rossum]

Guido van Rossum added the comment:

By the way I just looked at wait_for.py; it has a bug where do_work() isn't using yield-from with the sleep() call. But that may well be the issue you were trying to debug, and this does not change my opinion about the issue -- I am still looking forward to your patch.
