    Ensure editline cleanup occurs when Ctrl-C is pressed at control console.
    
    A recent change was made to avoid a race condition on shutdown which only called
    the end functions from the console thread. However, when pressing Ctrl-C the
    quit handler is called from the signal handler thread.
    
    (closes issue #17698)
