It seems fundamentally runtime to me, since different machines or just
different runs will want different levels of concurrency.  The
overhead ought to just be a few compares and arithmetic operations,
which would be swamped by the effort involved in the sorting.

I think normally I'd want to just use
parallel_sort(b, e, thread::hardware_concurrency())
