David Rowley ad9a23bc4f Optimize Query jumble 
f31aad9b0 adjusted query jumbling so it no longer ignores NULL nodes
during the jumble.  This added some overhead.  Here we tune a few
things to make jumbling faster again.  This makes jumbling perform
similar or even slightly faster than prior to that change.
