!IMPORTANT! New test patch for gamepad/dll issues

[someone972]

I'm not sure if it will help any, but I've narrowed down the time when it hangs for me to a specific point. When the sound is not working, it hangs at the call to SDL_WaitThread between "Stopping updater thread" and "Deleting sources", which is called from the sound shutdown function. When the sound does work it gets by it fine. I've still not determined what it is that makes the sound work some times and not others.
