Possible leak if someone were to try and add extra headers to a channel that had either an inbound info on that session or the session were to be deflected. I don't see a way that these extra headers could be added outside of a C module subscribing to the session states, but just to make sure I'm adding these so that just like other extra header locations it's cleaned up.
