Attached at_fork.patch: detect fork and handle fork. * Add _at_fork() method to asyncio.BaseEventLoop * Add _detect_fork() method to asyncio.BaseEventLoop * Add _at_fork() method to selectors.BaseSelector I tried to minimize the number of calls to _detect_fork(): only when the self-pipe or the selector is used. I only tried test2.py. More tests using two processes running two event loops should be done, and non-regression tests should be written. The issue #22087 (multiprocessing) looks like a duplicate of this issue.

I only tried test2.py. More tests using two processes running two event loops should be done, and non-regression tests should be written.
