When still in the original interpreter session, all the objects still exist in memory, so all the pointers stored in the array are still valid.

Do you think this persistence could affect xarray's tests? The way the tests work is via a context manager, like this python @contextlib.contextmanager def roundtrip(self, data, save_kwargs={}, open_kwargs={}, allow_cleanup_failure=False): with create_tmp_file( suffix='.zarr', allow_cleanup_failure=allow_cleanup_failure) as tmp_file: data.to_zarr(store=tmp_file, **save_kwargs) yield xr.open_zarr(tmp_file, **open_kwargs)

Do we need to add an extra step after data.to_zarr to somehow purge such objects?
