Hi Nick, This is really something you'd want to use a debug for - just run it and break the app before anything untoward happens.
The code itself looks quite benign on a first reading, the only thing I can think of that might cause a memory issue would be if your scene graph had a circular reference in it so the traversal ends up in an infinite loop.
