It would be interesting to compare running the program under pbsdsh to
running it with Pete Wyckoff's "mpiexec" program using the -comm=none
option (to stop it doing an MPI setup work).
pbsdsh /path/to/foo $ARGS
mpiexec -comm=none /path/to/foo $ARGS
I have a memory of Pete having to do some work around this in the last
6 months or so (but then my memory does suffer from random bitrot, so
it's always good to check..)
