[PATCH] Proposed Fix

I am somewhat concerned that other iterations over m_windowShells could trigger a GC that modifies m_windowShells. However they are far more straightforward than WebCore::ScriptController::clearWindowShell.

It also seems dangerous that ScriptCachedFrameData reaches directly in and iterates ScriptController.m_windowShells.
