I agree with Andy.  I think it was appropriate to send this series, since
(as far as I can tell) it's a completely different approach from the others
taken.  I'm not really qualified to judge whether the implementation is
good (it's a bit outside my competency as a reviewer), but the described
approach is more convincing to me than the other approaches.

Can we review this series properly?
