The main reason why CInputManager was singleton is the easy access across the code. That had the negative side effect that time of destruction was at a very late stage of the shutdown and could not be controlled by us. My moving it to CApplication, the access is equally easy (using sApp) and allows to be cleaned up properly during graceful shutdown. ref T391
