> When {{OfflineSorter}} needs to write a new file, either a temp file or the final sorted output file, it calls {{getWriter}}.  There is a default impl, but experts can override it to create their own writers.
> It would be helpful to pass the total item count that will be written to this file when calling {{getWriter}} because then the (expert) user has a little more information which can be useful when creating the temp or final file.
> It's low cost for {{OfflineSorter}} to track this.
