 // A browser plugin is a plugin container that hosts an out-of-process "guest"
 // RenderView. Loading up a new process, creating a new RenderView, navigating
 // to a given URL, and establishing a guest-to-embedder channel can take
 // hundreds of milliseconds. Furthermore, a RenderView's associated browser-side
 // WebContents, RenderViewHost, and SiteInstance must be created and accessed on
 // the UI thread of the browser process.
 //
 // To avoid blocking the embedder RenderView and to avoid introducing the
 // potential for deadlock, BrowserPlugin attaches a placeholder that takes
 // place of the guest RenderView until the guest has established a connection
