I ran the test on my single-core hyperthreaded system. If you have a
true dual-core system I'd be curious to hear your results.
After running in 60% of the time by splitting in half, sorting,
then merging the two halves, I tried burying the tasking inside
a quicksort. On the first partitioning, one of the partitions goes
to a separate task. That ran around 75%, perhaps because the
partitions are likely not the same size.
