[BUG] RuntimeError: Loop is not running

[DanielTsiang]

Versions:

fsspec                        2023.9.0
s3fs                          2023.9.0

On my Sanic app startup, I'm getting the following warning message:

/opt/python/lib/python3.10/site-packages/s3fs/core.py:546: RuntimeWarning: coroutine 'ClientCreatorContext.__aexit__' was never awaited
  loop.create_task(s3.__aexit__(None, None, None))

Which I think is then what is leading to this exception later on:

RuntimeError: Loop is not running

The RuntimeError did not appear previously on version 2023.6.0.

However, the error only seems to occur on app startup. The app seems to still work fine afterwards.
