WHY: When running OSU benchmark on 2 nodes and utilizing a larger

grow.  This is not a common case, but it is something that folks sometimes 
experiment with.  Also note that this minimum was set back 5 years ago so it 
seems that it could be time to bump it up.
WHEN: Tuesday, July 29, 2014 after weekly concall if there are no objections.
