    	Fixed: <rdar://problem/3161102>: Avoid retain cycles by destroying plug-ins in the page cache before dealloc
    
            Reviewed by rjw.
    
    	* History.subproj/WebHistoryItemPrivate.h: added declaration for [WebBackForwardList _clearPageCache]
            * WebView.subproj/WebViewPrivate.m:
            (-[WebView _close]): clear the page cache when we are closing the web view so we call destroy on all the plug-ins on the page cache to break any retain cycles.
