Here is how I think the future could develop

Cycle	SLAB		SLUB		SLOB		SLxB

2.6.22	API fixes	Stabilization	API fixes

Major event: SLUB availability as experimental

2.6.23	API upgrades	Perf. Valid.	EOL

Major events: SLUB performance validation. Switch off
	experimental (could even be the default) 
	Slab allocators support targeted reclaim for at
	least one slab cache (dentry?)
	(vacate/move all objects in a slab)

2.6.24	Earliest EOL	Stable		- 		Experiments

Major events: SLUB stable. Stable targeted reclaim
		for all major reclaimable slabs.
		Maybe experiments with another new allocator?

2.6.25	EOL		default		-		?

Death of SLAB. SLUB default. Hopefully new ideas on the horizon.
