Oh, then your time was not bad.  I just did some math, and it appears
that JtR would complete a similar run in about 50 minutes (that's on one
CPU core).  There got to be room for improvement here.

Well, 3.5x to 5.5x faster by using all four cores.  So far, this is best
done by running 8 instances of JtR manually (it should be 8 for a Core i7
with HT enabled even though the CPU is quad-core), but I'll need to be
improving the code to make this simpler yet efficient.
