I would like to be able to start a non-oversubscribed run of a program in
OpenMPI as if it were oversubscribed, so that the processes run in Degraded
Mode, such that I have the option to start an additional simultaneous run on
the same nodes if necessary.

After much more testing and banging my head on the desk trying to figure this
one out, it turns out '--mca mpi_yield_when_idle 1' on the command line does
actually work properly for me... The one or two times I had pr
