            // to start drawing. Normally, the WM animation system takes care of this, but here we

            // give the dream application some time to perform a custom exit animation.

            // If it uses a view animation, the WM doesn't know about it and can't make the activity

            // translucent in the normal way. Therefore, here we ensure that the activity is

            // translucent during wake up regardless of what animation is used in onWakeUp().

            // calls finish() immediately so there wouldn't be much point in telling
