Hi Adrian,

The OpenSceneGraph/examples/osgtext example has a code path that
includes use of UpdateOperation in the context of multi-threaded

If you run:

    osgtext --mt

You will seem a continuous random placement of osgText::Text labels
into a box using a custom osg::Operation in combination of
OperationThread ad Viewer::addUpdateOperation.
