These two tests have started failing semi-regularly.

dask/array/tests/test_array_core.py::test_setitem_extended_API_2d_mask[index1-value1]
dask/tests/test_distributed.py::test_blockwise_dataframe_io[False-False-hdf]

They're failling on Mac, and so should be easy to reproduce. I haven't been able to just yet though.

cc @jrbourbeau when you get back. Maybe also @rjzamora and @fjetter (and team) can take a look when they get back?
