mpi-testsuite currently reports

$ grep "^ok" /usr/share/mpi-testsuite/results/mpich/summary.tap | wc
     28     300    1805
$ grep "^not ok" /usr/share/mpi-testsuite/results/mpich/summary.tap | wc
    922    5526   33004
$ grep "^ok" /usr/share/mpi-testsuite/results/openmpi/summary.tap | wc
    681    3565   21965
$ grep "^not ok" /usr/share/mpi-testsuite/results/openmpi/summary.tap | wc
    237    1314    8780


Odd result, that set of "not ok" suggests mpich is the more buggy.
