I suspect what is happening is that when running something intensive
like a benchmark Squeak is getting basically uninterrupted attention
from one cpu and all the other work is going to the other core. What
this indicates is that about 30% of all the time on a single core
machine is being wasted on trivia like running the OS and all the
rest of the stuff that sits there sucking up cycles.
Now we have a basis for supporting Dan Ingall's old comment about OSs
and how there shouldn't be one :-)
