def do_exit(*args):
    '''
        We have to override the exit because calling sys.exit will only actually exit the main thread,
        and as we're in a Xml-rpc server, that won't work.
    '''

    try:
        import java.lang.System

        java.lang.System.exit(1)
    except ImportError:
        if len(args) == 1:
