Well my Computing Independent Study class (aka CIS(theta)) put
together our cluster (aka Shadowfax). Apparently they found
documentation on http://www.sagemath.org about using parallel python
or mpi4py in SAGE. Does that work?

Given that we don't do anything special with that library we should
probably point the user to its documentation rather than write
something ourselves.
