As I already mentioned, buffering for *logging* is different from
buffering for *printing*.

I think it might be a great idea to buffer for logging in order to
generate one individual buffer record there.

But it needs to be printed as it is generated.

The printing and the recording really should be thought of as separate
issues. You already record things that aren't printed, so they already
aren't 1:1 relationships.
