Async Queue Usage Example

gistfile1.txt

            var tree = new Y.ParentWidget({
               id: "tree"
            });

            tree.plug(Y.SM.Plugin.WidgetParentRenderQueue, {timeout:2000});
            
            tree.add([
               { type: Y.ChildWidget, id: "leaf-1", label: "Leaf One" },
               { type: Y.ChildWidget, id: "leaf-2", label: "Leaf Two" },
               { type: Y.ChildWidget, id: "leaf-2", label: "Leaf Three" },
               { type: Y.ChildWidget, id: "leaf-2", label: "Leaf Four" },
               { type: Y.ChildWidget, id: "leaf-2", label: "Leaf Five" },
               { type: Y.ChildWidget, id: "leaf-2", label: "Leaf Six" },
               { type: Y.ChildWidget, id: "leaf-2", label: "Leaf Seven" },
               { type: Y.ChildWidget, id: "leaf-2", label: "Leaf Eight" },
               { type: Y.ChildWidget, id: "leaf-2", label: "Leaf Nine" },
               { type: Y.ChildWidget, id: "leaf-2", label: "Leaf Ten" }
            ]);
            tree.render();

tree.render(); tree.add(); does bring out the issue. The above snippet doesn't.
