Well this is unexpected, the same code running on Linux is throwing
GeneratorExit-related mysterious exceptions as well. I'm not sure whether this
is the same problem, but this one has a clearer traceback. I will attach the
full error log, but the most pertinent part seems to be this:
During handling of the above exception, another exception occurred:
Traceback (most recent call last):
File "/usr/lib/python3.8/contextlib.py", line 662, in __aexit__
cb_suppress = await cb(*exc_details)
File "/usr/lib/python3.8/contextlib.py", line 189, in __aexit__
await self.gen.athrow(typ, value, traceback)
File "/opt/prettysocks/prettysocks.py", line 332, in closing_writer
await writer.wait_closed()
File "/usr/lib/python3.8/asyncio/streams.py", line 376, in wait_closed
await self._protocol._get_close_waiter(self)
RuntimeError: cannot reuse already awaited coroutine
closing_writer() is an async context manager that calls close() and await
wait_closed() on the given StreamWriter. So it looks like wait_closed() can
occasionally reuse a coroutine?
