[issue21998] asyncio: support fork

Antoine Pitrou added the comment: I'm not sure why it would be debug-only. You usually don't fork() often, and you don't have many event loops around, so the feature sounds cheap. In any case, I'm not directly affected by this issue, I'm merely suggesting options. -- ___
