Most of them will be SMP, correct? For SMP, 95% of the memory operations
occur in the per-cpu arrays. I'm not sure if a slab is really the right
backend behind the per-cpu arrays - perhaps a algorithms that's more
aggressive toward finding freeable pages would be a better choice, even
if it needs more cpu time for sorting/searching through the partially
allocated pages.
