This is an issue that occurs non-deterministically, generally during
client._reconnect at shutdown when peers have already begun closing.
Therefore it needs to be catched and raise CommClosedErrorto prevent
unhandled errors.

Given the non-deterministic nature of the issue, testing it is very challenging and unfortunately there's no known test that can be added currently.

Error handling depends on rapidsai/ucx-py#799 , but the change is backwards-compatible.

Thanks for the review @quasiben . I don't think errors are related, they're all on Windows runs and this PR exclusively modifies UCX which isn't even supported on Windows.
