Why put this on RenderProcessHost?  I would have thought you'd look up the
RenderViewHost and send the message from there.

[supersat, 2011/12/09 23:08:20]

The ProxyViewHost (which can send this message on behalf of its frame) doesn't
have a corresponding RenderViewHost. We also don't need anything specific to a
particular RenderViewHost to route the message to the right destination.

Ah, fair enough.
