From a cursory scan of the patches, this looks sane.

I'm not sure what the next step should be, but I really would like the
people who do a lot of pinning stuff to give it a good shake-down.
Including both looking at the patches, but very much actually running
it on whatever test-cases etc you people have.

Please?
