Talked with jst today about forcing inner windows to disappear whenever the outer window is closed. That way external refs to the outer window (from JS, mostly) wouldn't keep very many things alive.

As I understand it closed windows in JS are mostly useless husks anyway, so this would just let us do better internal memory management without really altering external behavior.

We'd then be able to remove the ShouldBeFreed CC hints in outer windows to avoid lots of false-positive warnings like in bug 423723.

Marking wanted but just as a P2, feel free to up the priority if we suspect this is a cause for many leaks.
