810 * region A which is (a_start,a_end)
813 * an empty buffer has: a_start = a_end = b_end = 0
816 * a_end is the pointer where we start writing data, unless it is BUFFER_SIZE,
819 * the buffer is full when b_end == a_start && a_end == BUFFER_SIZE
821 * there is room when b_end < a_start || a_end < BUFER_SIZE
823 * when reading, a_start is incremented, it a_start meets a_end, then
824 * we do: a_start = 0, a_end = b_end, b_end = 0, and keep going on..
