      We're spending cycles calling qsort() on typically small numbers of items, so I inlined the case where we have 2 items (wtperf's common case), and less than 11 items. A good implementation of qsort will simply do an insertion sort on small numbers of items anyway, but that still requires the qsort setup and then repeated calls to the qsort callback function.
