Yes, I recall @rabernat worked extensively on this. Possibly related: - https://github.com/pydata/xarray/issues/1340 - https://github.com/pydata/xarray/issues/1481

@shoyer , @rabernat , maybe if you have some time it would be good to revisit these issues and see if they can be closed?

I found that dask was version 0.11 on Windows but 0.15 on Linux. Upgrading the Windows version to 0.15 fixed the issue, indicating that the problem was the version of dask.

Is the dask version also identical on both systems?

Sorry about that, I've updated the second snippet. Also added more information in case it helps.
