I'm not sure it's such a hard decision. SLAB is on it's way out because
SLUB and SLQB code are much cleaner and the debugging support is better.
As for SLUB vs. SLQB, I'm hoping to trick you, Mel, and others into
doing an "epic slab allocator performance battle" and post the numbers
once we have have everything merged to mainline. My gut feeling is that
SLQB is in the lead because SLUB hasn't addressed the Intel regression.
