What about the case where my video player disables the screensaver and 
subsequently dies ? When using a "poke" or "beat" interface this is no 
problem and the screensaver will kick in again when appropriate. On the 
other hand if the screensaver is waiting for an "enable" call from my 
video player that never comes this will leave my desktop in an undesired 
state.
