I'm not sure multi-threading is the issue you think. Threads is, but
only for architectural reasons. Using multiple processes to complete a
task seems very sensible to me.

Yeh, sorting is isolated enough to try out some of those ideas on. I was
unaware of the work on finding medians, so thats a good way of dividing
the workloads for parallelism.
