Indeed (yet another reason why we should have anonymous buffers, which
can be GC'd without having to go through kill-buffer), but as mentioned
elsewhere I suspect that this use case will be rare, because when the
output wants to be in a buffer rather than a string you will likely be
able to do the replacement "in-place" without using a second buffer (and
hence without needing the diffing machinery of replace-buffer-contents).
