Trying to understand what was raising an exception with several methods associated to oocgcm grid objects that have been sliced (see), I have identified what I think might be an issue when slicing xarray.DataArray defined with dask chunks + lock=False.

A illustration of the issue can be found in this notebook. I am afraid my understanding of xarray/dask is not sufficient for me to suggest a fix.

This is a likely regression in dask:
