Test failure with latest distributed

[quasiben]

With dask/distributed#5814 merged in, the test_proxify_host_file.py::test_worker_force_spill_to_disk test currently fails test fails in due to assertion in distributed: https://github.com/dask/distributed/blob/39c5e8856cb05ad1833a0f6ee6c3fea0ddab1c1c/distributed/worker.py#L3882-L3884

self.data is <class 'dask_cuda.proxify_host_file.ProxifyHostFile'> and SpillBuffer is its own type. It seems like we could either ask why the assertion is necessary or subclass spillbuffer for ProxifyHostFile

Sorry, only saw this now. I believe this is a breaking change from Distributed for us, I filed dask/distributed#5909 as well.

Think this was fixed by PR ( dask/distributed#5904 ) included in distributed version 2022.03.0. Going to go ahead and close this out, but please feel free to reopen if needed.
