Sure...  I guess we could kick that from either direct reclaim or from
kswapd.  But, then we're basically back to the places where
shrink_slab() is called.

I think that means that we think it's preferable to integrate this more
directly in the VM instead of sticking it off in the corner of tmpfs
only, or pretending it's a slab.

Dunno...  The slab shrinker one isn't looking _so_ bad at the moment.
