The algorithm is easy to parallelize, but in the end we still have some rather large numbers, so memory will be our primary dominator. I'd expect to see a linear speedup if it was "perfectly parallel", but this does not come close to that.

@kabutz i just finalized the CSR (the new year break meant all this is taking longer than usual). Based on that review we may need to make some tweaks to the API doc, which should be quick to process. So it should be in the bag for 19.
