Good point.  I'm not sure how dealii would react to that.  It's also
possible that the state of affairs has changed in more recent versions
of dealii (also on my todo list).  I suppose we'd need to give it a try
to know.  If it does fail, I'd say a patch to dealii is called for,
since the presense of scotch ordering capability in MUMPS should not
prevent dealii from using the metis orderings in any way.
