        The Request.headers dictionary is not a documented interface.  It
        should stay that way, because the complete set of headers are only
        accessible through the .get_header(), .has_header(), .header_items()
        interface.  However, .headers pre-dates those methods, and so real code
        will be using the dictionary.

        The introduction in 2.4 of those methods was a mistake for the same
        reason: code that previously saw all (urllib2 user)-provided headers in
        .headers now sees only a subset.
