Brian Barrett 58b325b03f Two changes to improve the sm situation with spawn:
* have the mpool size be based on MCW, not num procs
    in other jobs we know about.  Solves the problem of
    the spawned job having a much bigger than needed
    sm file
  * Can't assume that "me" is in the list of procs
    passed to addprocs, so need to use slightly different
    logic and not go through all of add procs unless
    there's a proc in my job that isn't me.

This seems to greatly improve the situation, although
there still seems to be more of a slowdown through
MPI_INIT for the children (if there are more than one
child) than MPI_INIT for the parent if there are 'n'
children compared to 'n' parents.  Hopefully that
made sense ;)
