I did look at it, but the thing is horrible. I started on this
something like ten times, and always ended up running away screaming.
Some things are truly fixed (notably "order"), but most things end up
changing subtly halfway through the callchain.

I might look at it some more later, but people may have noticed that I
decided to just apply Minchan's original patch in the meantime. I'll
make an rc8 this weekend..
