Comment (by robe):

 I'm beginning to think this is a sunk cause - should we just have it use
 sphere?
 I was all happy until I went to cleanup my tests (to get rid of the
 additional order by which was preventing index from kicking in) and was
 able to trigger the index out of order problem again.  I'll confirm it's
 the forcing the spheroid that is causing this before we decide if we need
 to sacrifice this to make #3131 work.
