Ok. So MPOL_BIND on a single node. We would have to save the current 
memory policy on the stack and then restore it later. Then you would need 
a special call anyways.
Well the memory policy will already be set to MPOL_BIND at this point.
The slab allocator I think would just have to honour the node at the
object level.
Who set the policy? The parent process may have its own memory policy. If 
you set that then the earlier policy is lost.
