Sorry the hassle - sorted it all out the requestExitAndWait() was a red-herring.
The problem was fixed properly by setting the activity launchMode = singleTask Now my app (with all its multiple threads) handles the HOME key and the back key properly. I am not sure the GLSurfaceView class as it is currently is designed to support anything except singleTask mode?
