MWE for "Resource temporarily unavailable" error on sys.exit() immediately following channel close.

Run poetry install to install dependencies
Run ./run_server.sh to start the gRPC server
Run ./run_client.sh to run repeated gRPC requests

About 1/3 of the time, the following error is printed:

SystemExit: 0

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/usr/lib/python3.11/asyncio/events.py", line 80, in _run
    self._context.run(self._callback, *self._args)

BlockingIOError: [Errno 11] Resource temporarily unavailable

Removing the sys.exit(0) in run_client makes the error go away.
