dask/dask#10535 broke test_decide_worker_coschedule_order_neighbors:

            # No more than 2 workers should have any keys
>           assert sum(any(k in w.data for k in keys) for w in workers) <= 2
E           assert 5 <= 2

This is actually a regression in dask.order

I'll need to investigate a little to see how bad this is
