Also add some thoughts about the existing and new design. Note: an earlier design used the names "head" and "tail" for both sides of the buffer, but it appears awkward as these words may be understood in two forms (feed by head, output by tail, or make the newcomers wait at the tail of the queue). Also there were already a few functions in the code making use of either terminology. So better avoid this terminology and use "input" and "output" instead.
