Hi Will, can you review this?  

I realize this makes it easier to procrastinate cleaning up the callers of the
Receiver variant, but I need this to land 
http://codereview.chromium.org/10917234/, which is important enough I'd really
rather not have to block it on that yak shave :/

I'm going to shut my eyes, close my nose, and approve this CL.

LGTM.
