-If play() is called again kill old 'looping/playing' in favor

 of the new value. This deletes the timer and would fix possible
 shortage on timer resources
-A small friend to hook to an internal signal to avoid problems
 in Opie::Core::ODevice entering the event loop to wait for
 the sound to be finished. processEvents() can give strange results as
 some applications do not expect that the eventloop is entered. This
 could possible deliver a Timer, or an Event from QSocketNotifier
 which could give all kind of problems of wrong reentrancy.
 So let us avoid it.
