Fun! Since you're already using WebOb, you should
give webob.Response a try, which will handle your
headers in a sexier way. (If you start using
paste.httpexceptions and the middleware, you can
avoid manually sending headers altogether.)

The config global probably isn't thread-safe
depending on what you're doing with the
application. A safer way to go would be use Paste
Registry like Pylons does with its globals or just
attach it to Request.
