    We're heading in the right direction anyway.  I can now compute 1
million iteration in about 2 minutes (with +RTS -H750M -K100M).  Well
almost, since it now doesn't compute the right answer, so something must
be amiss in the shuffling section.  Now if we can get it to us a little
less than 1G of memory, we'll be in good shape.
