-// How ownership works
-// -------------------
-//
-// Big oh represents a refcounted relationship: owner O--- ownee
-//
-// WebView (for the toplevel frame only)
-// O
-// |
-// Page O------- Frame (m_mainFrame) O-------O FrameView
-// ||
-// ||
-// FrameLoader O-------- WebFrame (via FrameLoaderClient)
-//
-// FrameLoader and Frame are formerly one object that was split apart because
-// it got too big. They basically have the same lifetime, hence the double line.
-//
-// WebFrame is refcounted and has one ref on behalf of the FrameLoader/Frame.
-// This is not a normal reference counted pointer because that would require
-// changing WebKit code that we don't control. Instead, it is created with this
-// ref initially and it is removed when the FrameLoader is getting destroyed.
-//
-// WebFrames are created in two places, first in WebViewImpl when the root
-// frame is created, and second in WebFrame::CreateChildFrame when sub-frames
-// are created. WebKit will hook up this object to the FrameLoader/Frame
-// and the refcount will be correct.
-//
-// 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.
-//
-// Frame going away causes the FrameLoader to get deleted. In FrameLoader's
-// destructor, it notifies its client with frameLoaderDestroyed. This calls
-// WebFrame::Closing and then derefs the WebFrame and will cause it to be
-// deleted (unless an external someone is also holding a reference).
