    Don't exit on XSMP request
    
    It looks amazingly lame if we simply call exit() during logout.  While
    it's true that for applications that use XSMP, gnome-session will
    close them before us, that doesn't do anything for non-XSMP apps,
    which we really hope is the common case.
    
    Instead, we just go away when the X server does.
