Circling some off-list comments back to the list...while we could and
should error-out easier, this really isn't a supportable operation.
What the cmd
mpirun -n 2 -slot-list 1,3 foo
appears to do is cause us to launch a 2-process job consisting of
vpid=1 and vpid=3, as opposed to the normal vpid=0 and 1.
Not only is ORTE not prepared to handle this scenario, I believe it
will cause problems in some areas within OMPI.
I can try to make it fail nicer - someone with more knowledge of the
intended slot-list behavior would have to make it do what they
actually intended, or at least explain what is supposed o happen.

Sigh - you really need to remember to tell us what version you're
talking about.
