Including producing a full blown log file with an awful lot of
statistics it took 2 seconds on my 60 mhz PowerPC601 machine.
Iteration 7, 43914 nodes, minimal hashtable (128 K entries).
This time includes clearing the hash table.

Without the hash table it took 3 seconds, iteration 7, 77162
nodes. I believe that things like these can be solved easily
much faster with better selectivity.

Is there anything special about that problem ?
