Maybe it is just the processor speed, but maybe there is a 
also a difference between Intel and PPC macos, or the fact 
that I have Darwin 8.10.1.  Just thought, it might be useful 
to have an additional data point.

In any case, let me know if there is anything that you'd 
like me to try or have a look at on macos to track this down.
