-// 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
-// with its embedder RenderView. This permits asynchronously loading of the
-// guest while the embedder RenderView is permitted to continue to receive and
-// process events.
-//
-// Furthermore, certain navigations can swap to a new guest RenderView on an
-// different process. BrowserPlugin is the consistent facade that the embedder's
-// WebKit instance talks to regardless of which process it's communicating with.
