Ugh, I've been hoping you would forget about this :)

But, in thinking a lot about this recently, I have now come to the same
conclusion as you, I think we really need this as there isn't a way to
handle it any other way.

So, can you rebase and resend these patches? I don't have them in my
queue anymore and I'd like to play with them and see how they work.

thanks,
