* embeddedDispose should be called before the applicaton terminates the
* Java VM. It is currently unsafe to reinitialize the toolkit again
* after it has been disposed. Instead, awt.dll must be reloaded and the
* class loader which loaded WToolkit must be finalized before it is
* safe to reuse AWT. Dynamic reusability may be added to the toolkit in
