So I'm not interested in seeing *another* KSM version.

Because I absolutely do *NOT* want a new chapter in the saga of SLUB
vs SLAB vs SLOB.

However, if the feeling is that this can *replace* the current horror
that is KSM, I'm a lot more interested. I suspect our current KSM
model has largely been a failure, and this might be "good enough".
