[issue39010] ProactorEventLoop raises unhandled ConnectionResetError

Here is another way to reproduce this (or an extremely similar) error without a loop. Since may be a race condition, I'm not sure this works 100% of the time on all machines - but it did on several machines I tried.

```
import asyncio

loop = asyncio.get_event_loop()

def func():
    pass

f = loop.run_in_executor(None, func)
loop.stop()
loop.run_forever()
loop.stop()
loop.run_forever()
loop.stop()
loop.run_forever()
```

```
Error on reading from the event loop self pipe
loop: <ProactorEventLoop running=True closed=False debug=False>
Traceback (most recent call last):
  File "C:\Miniconda3\envs\py38\lib\asyncio\windows_events.py", line 453, in finish_recv
    return ov.getresult()
OSError: [WinError 995] The I/O operation has been aborted because of either a thread exit or an application request

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "C:\Miniconda3\envs\py38\lib\asyncio\proactor_events.py", line 768, in _loop_self_reading
    f.result()  # may raise

    value = callback(transferred, key, ov)
  File "C:\Miniconda3\envs\py38\lib\asyncio\windows_events.py", line 457, in finish_recv
    raise ConnectionResetError(*exc.args)
ConnectionResetError: [WinError 995] The I/O operation has been aborted because of either a thread exit or an application request
```
