Hi Alasdair,

Sorry for confusing you.

I had sent those three sets in the order above since 1 enhances 2 and 3.
But 2 and 3 don't functionally depend on 1 (although 1 and 3 have
a few cosmetic dependencies), so we can reorder that as we want.

2 and 3 are simpler patches than 1, and I found some problems in 1,
so I think reordering might be a good idea if you are OK.
As for 3, I still want to get feedback from others as it'll involve
discussion about the optimal interface for load balancer.

Thanks,
