Given proper OS support, this seems workable. However, note that the 
behavior of a thus implemented time event would not be in line with the UML 
specs. Pre-2.0 UML pretty clearly states that a time event is only 
dispatched when the FSM has been residing in a state for the specified 
amount of time *and* a transition triggered by a time event originates at 
said state.

HTH,
