        Speculative fix for
        <rdar://problem/5839800>
        CrashTracer: [USER] 5802 crashes in Safari at com.apple.WebKit: -[WebHTMLView(WebPrivate) _updateMouseoverWithFakeEvent] + 389

        Set _private->closed to YES before calling -[WebPluginController destroyAllPlugins].

        My theory is that the plug-in destruction callbacks could end up rescheduling timers or re-adding notifications.
        This is usually protected by _private->closed, but in this case it might still be false.

        (-[WebHTMLView close]):
