Jeff, you should really learn Python and give a try to mpi4py. Even if
you do not consider Python a language for serious, production work
:-), it would be a VERY productive one for writing tests targeting
MPI. However, mpi4py have a BIG issue: not enough man-power for
writing decent documentation.

So you are suggesting my code could be buggy? No way ! ;-) . Slightly
more serious: almost all my bug reports were discovered while
unittesting mpi4py and getting failures when running with Open MPI, so
I'm really confident about my Python bindings.
