OK, so these figures make an even stronger case for my conclusion :-)
Single traversal can be much faster than multiple traversals *when
done right*.
Did you use +RTS -N2 on your program (or whatever it is that makes GHC
actually use multiple threads? or is that not necessary?) Anyway I
assume you wouldn't get better than 9.0s, which is still much worse than
2.2s.
