ParallelExecutor is a "service that allows work to occur in parallel
using a thread pool". I doubt it's usefulness in your case. Simply
create a new service, spawn threads in it as needed to do work and
implement a few get status operations that your page(s) can call. That
way, keeping the page up-to-date via AJAX is a separate concern.
