So to be clear:
if nothing is specified, we map-by socket and rank-by slot
if map-by is specified, we will also rank-by as that seems to be
the user expectation (based on feedback on the user/devel lists)

I actually asked Ralph to make one more change. The default MCW rank ordering
was to match the mapping. So in the np>2 case, on a 2 socket system, we'd
order like this:
-
[savbu-usnic-a:01121] MCW rank 0 bound to socket 0[core 0[hwt 0-1]]:
[BB/../../../../../../..][../../../../../../../..
