.. and then please run them in conjunction with somebody doing "make -j16" 
on the kernel at the same time, or just generally doing real work for a 
few days before hand.

The point is, there are benchmarks, and then there is real life. If we 
_know_ some feature only works for benchmarks, it should be discounted as 
such. It's like a compiler that is tuned for specint - at some point the 
numbers lose a lot of their meaning.
