HI Bruno,

Make sure you are using ref_ptr<> in your ReadFileCallback for any
scene graph data structures so if you remove nodes from the main scene
graph they don't get deleted mid load.  If you do this properly then
there should be no need to mess around with blocks that would
complicate the code.
