So, with the scala ForkJoinPool even when provide a thread factory, it sets
the thread names based on the "workerNamePrefix" (which is final) inside of
"registerWorker" which is called when constructing a new ForkJoinWorkerThread -
although with a custom factory we can change the name back after the thread has
been constructed.
