PNS: Let's make the r-tree work for us 

I'm not sure where the magic number of "4x worst" came from, but it's
been around forever.  This is extremely inefficient as it negates much
of the power of r-tree filtering in dense designs.  If we really trusted
it, we could set this just to worstClearance.  Keeping it above the worst
clearance by a little bit seems to provide enough of a speed improvement
to resolve the test cases I have, so I'll go with that for now.
