Its some overhead for SLAB (a lot is what? If you tune down the per cpu
caches it should be a couple of pages) but its none for SLUB. Maybe we
need to add the merge logic to SLAB?

Or maybe we can extract a common higher handling level for kmem_cache
from all slab allocators and make merging standard.
