// The input script function in the skull scene does busy wait
// for the sound effect, which is played after completing the
// song, to finish. To avoid too much CPU use, we add some slight
// delay here.
//
// Also the Ninteno DS backend seems only to update the sound, when
// either OSystem::updateScreen or OSystem::delayMillis is called.
// So we have to call delay here, since otherwise the game would hang.
