> Looking at Otis's sort problem on the mailing list, he said:
> {noformat}
> * looked for other places where this call is made - found it in
> MultiPhraseQuery$MultiPhraseWeight and changed that call from
> ArrayUtil.quickSort to ArrayUtil.mergeSort
> * now we no longer see SorterTemplate.quickSort in deep recursion when we do a
> thread dump
> {noformat}
> I thought this was interesting because PostingsAndFreq's comparator
> looks like it needs a tiebreaker.
> I think in our sorts we should add some asserts to try to catch some of these broken comparators.
