 * the OS, it will return false results if the application you are
 * running doesn't follow these conventions. One notable
 * exception is the Java VM provided by HP for OpenVMS - it will
 * return 0 if successful (like on any other platform), but this
 * signals a failure on OpenVMS. So if you execute a new Java VM
 * on OpenVMS, you cannot trust this method.</p>
