Just to confirm: DOMWindowProperty has LocalFrame* and DOMWindow*, but these raw
pointers are no problem because they are cleared in
DOMWindowProperty::willDetachGlobalObjectFromFrame(), right?

(These raw pointers would be no problem because ApplicationCache is still
"RefCounted"GarbageCollected. I want to make sure that they are no problem even
if we change it to GarbageCollected.)
