    I'm really suprised this is still the default.  I've heard mention of
    this at least 4 years ago, and have seen trojaned SSH servers around
    _since then_ that do logging of client X11 keystrokes - probably the
    best place to accomplish this.  The problem seems to be that the
    authors have not figured out that this isn't a good default, perhaps
    for convenience's sake.  This suprises me, since people DO know about
    this.  I think the argument is really convenience vs. security (well,
    thats always the argument isn't it?).
