Mainline and mm it seems, only if NUMA is ON, on 2.6.17 only (2.6.16.XX 
is OK)

I added some printks and it seems slab_partials is not empty in 
__node_shrink() for node 0

I am not a mm/slab.c expert but the following patch cures the problem 
for me :

[PATCH] slab : NUMA may need __cache_shrink() doing two loops.
