Re: Emacs routinely gets stuck in single_kboard mode

[Richard Stallman]

            Please wait; this keyboard is locked by activity on the foobar:0 
display

    and 2) pressing C-g would pop up a (faked?) y-or-n-p with a variation
    of the following prompt (but better worded):

            Break the lock?  (Warning, the effects may be unexpected) (y or n)

    Pressing C-g again would cancel the prompt and leave Emacs in
    single-keyboard state, so the user would not accidentally break the
    lock.

I think that is not hard enough to do by accident.  It would
cause problems.

How about if it displays one message, discards all input, displays
another message, then asks for input?  That could be harder to do by
accident.  Maybe it could even discard input twice, separated by one
second?
