Comment (by cypherpunks):

 I have the suspicion that not even disabling javascript would completely
 prevent this... I'm thinking of the CSS hack that allows fingerprinting
 the screen size, I imagine something similar could probably be done to
 detect the transitions of this "timer", without any need of js.
