> The inner loop of the sort is calling progress on each compare. I think it
> would make more sense to call progress in the sort rather than the compare or
> at most every 10000 compares. In the performance numbers, the call to
> progress as part of the sort are consuming 12% of the total cpu time when
> running word count under the local runner.
