- *
- * basically, we use two circular buffers, each one corresponding to a given
- * direction.
- *
- * each buffer is implemented as two regions:
- *
- *   region A which is (a_start,a_end)
- *   region B which is (0, b_end)  with b_end <= a_start
- *
- * an empty buffer has:  a_start = a_end = b_end = 0
- *
- * a_start is the pointer where we start reading data
- * a_end is the pointer where we start writing data, unless it is BUFFER_SIZE,
- * then you start writing at b_end
- *
- * the buffer is full when  b_end == a_start && a_end == BUFFER_SIZE
- *
- * there is room when b_end < a_start || a_end < BUFER_SIZE
- *
- * when reading, a_start is incremented, it a_start meets a_end, then
- * we do:  a_start = 0, a_end = b_end, b_end = 0, and keep going on..
