I too see some anomalies.  I've run the test on 4 machines and here
are my pictures:

The best is 3454 seconds.  With 4 CPUs in the Sun Fire V440 and 2
in the V20z I look forward to an rpiece benchmark test!


I can't seen what is causing the black shadows.  Next I will try
some different settings - and rpiece for multi-CPU speed.
