Summary: Not using dual core chip correctly on Benchmark

Initial Comment:
I have run the benchmark routine on a new Intel Core 
Duo on a MAC mini.  I noticed that it only utilized 
one of the cores.  In the past I have noticed that it 
will utilize all of the CPU's on a machine.

Yeah, this is a known issue that should be fixed in one of the upcoming 
releases.  The issue stems from the code that detects the number of CPUs 
being tied to a PPC section and that instead neads to be bound to something 
more generic (detection of the posix sysctl() call availability).

Another related issue is that if you disable a CPU with the CHUD tools, the 
ray-trace library doesn't perform the correct accounting.  Apple had  
recommended and provided code for a fix for that issue, but it hasn't yet 
been applied and tested sufficiently yet.
