This change amounted to dead code removal, so I'm not sure how it could
have an effect.  There were only a couple places where the changes were
other than mechanical in nature.  Also, that the number of cores matters
is no less puzzling.

Can you send Kostik and me the output of "sysctl vm.stats.vm" from
shortly after boot on the kernel with the patch reverted?
