My question is why? If you are willing to reserve a chunk of your
machine for yet-to-exist tasks, why not just create them all at mpirun

I can't imagine how you would do that - only thing I can think of would be to
start your "child" processes as one job, then start your "parent" processes and
have them do an MPI_Comm_join with the child job.
That said, I can't imagine that comm_spawn is -that- slow to make much
difference to
