Even simpler, the following code will crash after so many iterations:


```
import asyncio
loop = asyncio.get_event_loop()

while True:
    loop.call_soon_threadsafe(loop.stop)
    loop.run_forever()
```

Adding a little sleep of 0.01s after `run_forever()` prevents the issue.

So, to me it looks like the cancellation of the `_OverlappedFuture` that wraps around the `_recv()` call from the self-pipe did not complete before we start `_recv()` again in the next `run_forever()` call. No idea if that makes sense...
