Unless someone else has looked into this, I am playing with some ideas
about how to make the SLAB ride on top of Guarded Page Tables with software
enforced page sizes as low as 16 bytes. A variable page size impl that deals
well with a sparse address space (as for the 64bit ports) lends itself even
better to the SLAB than the buddy system methinks.
