OK in principle; one question below:

Does this still iterate through things in the same order?  That's
important, IIRC.  I couldn't quite follow the changes to build up and
iterate through these lists, but would you please double-check?  If you
do need to reverse the iteration, that's an obvious change; just post
the final patch after check-in.

Thanks,
