On the Unix platforms, we had to implement a workaround to this problem
for Firefly. Please remove the changes made to the following files
in the indicated deltas...

   update: ext/plugin/java/src/sun/applet/ActivatorAppletAudioClipRef.java 1.4
   update: ext/plugin/java/src/sun/plugin/ActivatorAppletContext.java 1.7

Then follow these steps...

Run Netscape 4.x...

1) Visit http://webwork.eng.sun.com/products/plugin/1.3/demos/applets.html
2) Choose '3D Chemical Models'
3) Hit back
4) Choose 'TicTacToe' and play a game
5) Hit back
6) Hit 't' in the java console and you will see the tictactoe threads still alive

This is causing a download on ref.get() in ActivatorAppletContext.stopAudioClips(). This is causing the deadlock.
