Yes, this Node will never be deleted. You can force it to be deleted by
using a RefPtr to store it.
RefPtr<NodePtr> willBeDeletedNode = Node::create();
// this node exists and has a refcount of one
When the willBeDeletedNode goes out of scope the refcount will be
decremented and the node will be deleted.
Hope it helps
Dirk
