Nasty one. We stash input data, so if the actual disk data from which the input was read goes away, we don't notice. Except we do when an undo occurs, because it tries to run the input again and there's no data to read. At least, that's what I think is happening.
If that's the case, we need the input to keep its data in this case, but a warning to show.
