The revalidation logic in type_run() still looks wrong.  The previous
version of the code:

        1. Saves copies of revalidate_set and need_revalidate.
        2. Clears revalidate_set and need_revalidate.
        3. Uses the copies to revalidate.

The new version appears to:

        1. Clear revalidate_set and need_revalidate.
        2. Use the cleared original versions to revalidate.

Otherwise this looks good (modulo what Reid noticed), thanks.
