We had a bit of followup later:

    http://email.osc.edu/pipermail/mpiexec/2004/000329.html

but I never did anything because I wasn't sure what the right
behavior would be.  And there seemed to be some question about
modifications to qsig too.

If you and others can figure out all the details and handle
the PBS side of things, I'll certainly help to get mpiexec
to play nicely with SIGSTOP and SIGTSTP.
