Why not first deal with sending STOP to the other processes, and when
done with that, sending a STOP to mpirun, so it stops as well?
BTW, sending STOP to processes rather than TSTP will prevent them from
being able to do similar to user processes of their own. Dunno how
useful or practical that is for OpenMPI users.
