The ResponseEnumerator itself is in charge of the entire process,
including running the Iteratee. So in pseudo-code, you'd do something

ResponseEnumerator $ \mkiter -> do
    handle <- getHandle
    run_ $ enumHandler handle $ mkiter status headers
    hClose handle

I think we could make that functionality optional, based on an extra
setting parameter. Would this just be boolean, or is more
sophisticated control required?
