SF kept a strong reference to ISurface until the window manager removed the surface from the screen. This fell appart when running standalone tests, that is when the window manager wasn't involved. When the window manager is around, it would clean-up surfaces even when an application died. with this change, SF is able to do its own cleanup without relying on the window manager. the change is very simple, we simply don't keep a reference to ISurface and make sure no more than one of them can be created.
