Using mpi4py, you have access to almost all MPI internals directly
from the Python side, with an API really similar to MPI-2 C++ bindigs.
This is a feature I've not seen in other Python bindings for MPI. I
think this is really important for developers and people learning MPI;
you do not need to learn a new API.
