 // 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 WebContents (browser) which
 // are correlated with IDs. This way, the Views and the corresponding ViewHosts
 // communicate through the two process objects.
