Balbir, how would you want to do ?

I planned to post shrink_uage patch later (it's easy to be implemented) regardless
of acceptance of this patch.

So, I think we should add shrink_usage now and drop this is a way to go.
I think I can prepare patch soon. But I'd like to push handle-swap-cache patch
before introducing shrink_usage.

Then, posting following 2 patch for this week is my current intention.
[1/2] handle swap cache
[2/2] shrink_usage patch (instead of this patch)

Objection ?

Thanks,
-Kame
