andi,

i really think it's time to write some engine-level benchmarks (loops 
etc) so we can actually see the improvement.

even though i really think that the VM-loop should be generated and not 
done thru cpp-magic i think committing it is a "step forward" 
.remember, sterling and i had a patch for this (& more) more than a 
year ago...

what's next?
