Right now, I do believe that if you list a host more than once, it bumps
the slots count. This is somewhat inelegant, but something like:
shell$ mpirun -host node1 -host node1 ...
Same as:
shell% mpirun -host node1,node1 ...
Will make node1 have a slot count of 2. We can certainly change this,
though -- it wasn't implemented simply because I didn't think of this
case. :-)
