We don't have to have an endless loop. We can decide to stop the loop
at any point. Since such inf-loop would be an error in any case it's
perfectly OK to end up with an "incorrect" display.
Currently we decide to stop the loop before it can even start, so we end
up with an incorrect display even if there would not be any such
inf-looping.
