In my particular application it'd be quite helpful if I could return
Chunked-Body responses (especially ones with additional trailing
headers). Since WSGI rules the use of transfer encodings, then it should
have a mechanism to request this sort of behavior aka, yield a "flush"
object that has optional trailing headers that should be included in the
chunk that is returned.
