- Use ``hash()`` rather than ``id()`` when computing the "phash" of a

  custom route/view predicate in order to allow the custom predicate
  some control over which predicates are "equal".

- Use ``response.headerlist.append`` instead of
  ``response.headers.add`` in
  ``repoze.bfg.request.add_global_response_headers`` in case the
  response is not a WebOb response.
