   The failing pickle test is only when using the `cloudpickle` module instead of the python pickle module. Perhaps they don't support cython3.0.0 yet? This is the only test in the entire codebase that tests cloudpickle.. not sure how important it is as a dependency to pyarrow.
   
   ```
   @pytest.mark.pandas
   @parametrize_legacy_dataset
   def test_cloudpickle_dataset(tempdir, datadir, use_legacy_dataset):
       cp = pytest.importorskip('cloudpickle')
       dataset = _make_dataset_for_pickling(tempdir, use_legacy_dataset)
       _assert_dataset_is_picklable(
           dataset, pickler=cp, use_legacy_dataset=use_legacy_dataset)
   ```
