    - Introduce a sysctl to control the default tty queue size kern.tty.qsize,
      which defaults to 1024 as before.
    - Add two ioctls TIOC{G,S}QSIZE to read and adjust the queue size on
      individual ptys.

    NB: ttys (and ptys) still silently (or beepingly (IMAXBEL)) drop
        characters if the queue size is exceeded. I.e. you can appear
        to succeed writing to the {p,t}ty, but not all characters will
        have made it if the queue overflows.  CVS:
