commit c22e4adc07305d0ff39756843015be6b092cbcb6

    Using SIOCOUTQ to flush output on client socket close caused a hard hang.
    
    To replicate the problem:
    
    (1) Check out the parent of this revision.
    
    (2) Run "gpsd -n -N -D 3 /dev/ttyUSB0" substituting the device as needed.
    
    (3) Run the following script in another window:
    
    while true
    do
      date
      ./gpspipe -n 3 -R -o /dev/null # hang if gpsd is sick
      ./gpspipe -d -R -o /dev/null
      sleep 2
      DELAY=$RANDOM      # 0-32K
      #usleep ${DELAY}00  # 0-3 seconds
      sleep  `echo "scale=6; $DELAY / 1000000" | bc`
      killall gpspipe
      #ps ax | grep gpspipe
    done
    
    (4) Run gpsmon in a third window.
    
    gpsd will hang in 3-5 minutes, requiring kill -9, in the kernal hrtime
    function.
