Well, textrun invalidation is (relatively) cheap. If we then don't need to _reconstruct_ the textruns for the text outside the visible part of the textarea, things would be fast.
But give comment 9 and comment 11, it sounds to me like we reconstruct textruns multiple times when enter is pressed. Or something.
