  SVN rev 198223 on 2009-10-19 07:17:37Z by ed
  
  Properly set the low watermarks when reducing the baud rate.
  
  Now that buffers are deallocated lazily, we should not use
  tty*q_getsize() to obtain the buffer size to calculate the low
  watermarks. Doing this may cause the watermark to be placed outside the
  typical buffer size.
  
  This caused some regressions after my previous commit to the TTY code,
  which allows pseudo-devices to resize the buffers as well.
