Formats a response entity.  Returns a tuple of the desired
status code and the formatted entity.  The default status code
is passed in, as is a dictionary of headers.

:param status: The default status code.  Should be returned to
               the caller, or an alternate selected.  The
               status code should include both the number and
               the message, separated by a single space.
:param headers: A dictionary of headers for the response.
                Should update the 'Content-Type' header at a
                minimum.
:param environ: The WSGI environment for the request.
:param bucket: The bucket containing the data which caused the
               delay decision to be made.  This can be used to
               obtain such information as the next time the
               request can be made.
:param delay: The number of seconds by which the request
              should be delayed.
