    That's incidentally exactly what the slab does, no need to reinvent
    the wheel for that, it's an old problem and there's room for
    optimization in the slab partial-reuse logic too. Just boost the order
    0 page size and use the slab to get the 4k chunks. The sgi/defrag
    design is backwards.
