The attached patch makes Locks, Conditions, Semaphores, and BoundedSemaphores support new 'async with' syntax.

Because the patch contains a file that will only be checked in to the CPython repo (, I decided to create the issue on instead of asyncio GH repo.

Please review.

Updated patch is attached:

- '__aenter__' returns None
- "with await lock" is now supported.
