Well, I suggest to attempt fixing logging.

The reference cycle in asyncio.Task.set_exception() is *by design*. It's really trick to fix it. Since the creation of asyncio, nobody managed to find a solution to fix it. Once I propose to create an asyncio task forcing a GC collection every minute, but it was never implemented.

If you have a clever idea to fix Task.set_exception() design, please open a separated issue.
