the thing that causes me troubles is the user data. I ran into a case of making the scene graph cyclic. I store in user data some nodes, so it ended up into infinite loop when adding a new view (startThreading sets this to a value). So my point is to have something like
"if (node->getThreadSafeUnref() != newVal) node->setThreadSafeUnref(newVal))" I know I can override this in my own class and implement it. Since this is called once in a while, I dont think it will be big overhead.
