Exiting from acme while win still running left processes over.

    removing RFNOTEG is not the answer.
    for example if i run cdfs and then
    type a DEL at the shell prompt,
    cdfs should not die.  
    
    win should notice the exiting of acme,
    not expect the note.

    It doesn't remove RFNOTEG for others servers but win
    and cleans things up even when one drastically deletes the acme rio-window.
    Still a hack, let you figure out a better solution.
