Ah, I think I know why the seg faults are still occuring. By default, dask.array.from_array uses a thread lock that is specific to each array variable. We need a global thread lock, because the HDF5 library is not thread safe.

@mrocklin maybe da.from_array should use a global thread lock if lock=True? Alternatively, I could just change this in xray -- but I suspect that other dask users who want a lock also probably want a global lock.
