It took me 1 year, a few sleepless nights, multiple attempts to understand the leak, but I eventually found it! WSASend() doesn't release the memory if it fails immediately. I wrote PR 11469 to fix the memory leak. ReadFile() has the same bug, I also fixed it.

By the way, the _overlapped.Overlapped type has no traverse function: it may help the garbage collector to add once, since asyncio is famous for building reference cycles by design (Future.set_exception()).
