In my opinion, the design flaw is that line buffering exists.  Indeed,
any kind of buffering other than `full'---unbuffered output should just
be a last-resort-buffer-size-equals-one trick, much the way I
implemented it myself---is just a complication that leads to this sort
of bad behaviour.

But there is nothing I can do about that. . . .
