this applies to examples/mpi/overview.ipynb and possibly to any ipyparallel-based notebook tested via nbval

random failures seem to be happening due to this issue in ipyparallel

we're not totally sure this is the actual issue, but it's more than a weak conjecture

currently worked around by adding NBVAL_IGNORE to all non-output cells. This seems to make CI happy for now...

horrible, but we might consider using flaky ... better than nothing?

integration with NBVAL is still missing though
