Indeed, and considering that we're all busy with the CF, I think it's
quite unreasonable of you to expect that we'll drop everything else
to think about this problem right now. The reason it's like it is
is that it's not easy to see how to make it better; so even if we did
drop everything else, it's not clear to me that any plan would emerge
anytime soon.
