-// 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).
