-// Implements a concrete RenderProcessHost for the browser process for talking
-// to actual renderer processes (as opposed to mocks).
-//
-// Represents the browser side of the browser <--> renderer communication
-// channel. There will be one RenderProcessHost per renderer process.
-//
-// This object is refcounted so that it can release its resources when all
-// hosts using it go away.
-//
-// This object communicates back and forth with the RenderProcess object
-// running in the renderer process. Each RenderProcessHost and RenderProcess
-// keeps a list of RenderView (renderer) and TabContents (browser) which
-// are correlated with IDs. This way, the Views and the corresponding ViewHosts
-// communicate through the two process objects.
