Sorry, I shouldn't have said that.  Kenny's original patch was
basically an implementation of something I'd suggested on IRC,
so the ultimate blame does lie with me.

I think the upshot is still the same: I don't really have time
to work on this, and given that what I suggested was either wrong,
or exposed some other latent problem, I think reverting the patch
is the correct thing to do under the circumstances.  I suggest that
someone else looks at the problem that the patch was trying to solve
(which AIUI was a pessimisation rather than a wrong-code bug).

Richard
