You suggested to behave as if truncate-lines is turned on when we discover a line whose rendering takes too long. I'm saying that doing so will prevent users from seeing more than a hundred or so characters of every line, and hide the rest. And that might be too drastic a measure, because Emacs becomes slow on lines much longer than 100 or 200 characters; a single very long line will only make it slow for that single window-full. IOW, the punishment is too severe, IMO.
