  Properly terminate the receive buffer before sending to iksemel.
  
  aji_io_recv takes the maximum number of bytes to read (instead of the total
  buffer size), so we have to subtract 1 from our buffer size.  Without this, when
  we receive packets that are larger than our buffer, iksemel will choke and
  things get wonky.
