-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.
