I ran slub/lockless through some stress testing and it seems to be quite 
stable on my testing cluster.  There is about a 2.3% performance 
improvement with the lockless slowpath on the netperf benchmark with 
various thread counts on my 16-core 64GB Opterons, so I'd recommend it to 
be merged into 3.1.
