The version at:

http://svn.python.org/projects/peps/trunk/pep-3333.txt

still shows:

        elif not headers_sent:
             # Before the first output, send the stored headers
             status, response_headers = headers_sent[:] = headers_set
             sys.stdout.write('Status: %s\r\n' % status)
             for header in response_headers:
                 sys.stdout.write('%s: %s\r\n' % header)
             sys.stdout.write('\r\n')

so not using buffer there and also not converting strings written for
headers to bytes.
