Re Autotuning: SLUB obj per page:
SLUB can combine pages of different orders in a slab cache so this would
be possible.
per CPU freelist per page:
Could we drop the per cpu partial lists if this works?
Clearing memory:
Could exploit the fact that the page is zero on alloc and also zap
when no object in the page is in use?
