-// How ownership works
-// -------------------
-//
-// Big oh represents a refcounted relationship: owner O--- ownee
-//
-// WebView (for the toplevel frame only)
-//    O
-//    |           WebFrame
-//    |              O
-//    |              |
-//   Page O------- LocalFrame (m_mainFrame) O-------O FrameView
-//                   ||
-//                   ||
-//               FrameLoader
-//
-// FrameLoader and LocalFrame are formerly one object that was split apart because
-// it got too big. They basically have the same lifetime, hence the double line.
-//
-// From the perspective of the embedder, WebFrame is simply an object that it
-// allocates by calling WebFrame::create() and must be freed by calling close().
-// Internally, WebFrame is actually refcounted and it holds a reference to its
-// corresponding LocalFrame in WebCore.
-//
-// How frames are destroyed
-// ------------------------
-//
-// The main frame is never destroyed and is re-used. The FrameLoader is re-used
-// and a reference to the main frame is kept by the Page.
-//
-// When frame content is replaced, all subframes are destroyed. This happens
-// in FrameLoader::detachFromParent for each subframe in a pre-order depth-first
-// traversal. Note that child node order may not match DOM node order!
-// detachFromParent() calls FrameLoaderClient::detachedFromParent(), which calls
-// WebFrame::frameDetached(). This triggers WebFrame to clear its reference to
-// LocalFrame, and also notifies the embedder via WebFrameClient that the frame is
-// detached. Most embedders will invoke close() on the WebFrame at this point,
-// triggering its deletion unless something else is still retaining a reference.
-//
-// Thie client is expected to be set whenever the WebLocalFrameImpl is attached to
-// the DOM.
