For the Match/MatchSuccess and MatchAll/MatchAllSuccess case, you also define
case, can you also define a 3rd message type to for the renderer to send to the
browser to Ack receipt of the Success message. I think we need an akc to
transfer ownership of the blobhandles embedded in these messages (so the browser
knows it can drop the handles its got open for them).

[gavinp, 2014/09/03 18:35:24]

That's reasonable, but right now we intend to add blobs to Responses on a
downstream CL rather than this one, there's a TODO in the content side of this
to that effect. Should we add a TODO somewhere in here?
