    I had the exact same problem on one of our BSD/OS 2.0 machines
last week.  I got a reply back from Matt Bush (xomox@boris.eden.com)
saying to use "stty -f <path-to-dev-entry> flushout" to drain the
output queue.  That solved the problem immediately.

    We don't seem to have "flushout" with the 2.0.5 stty though.  :(

NAME
     stty - set the options for a terminal device interface
[...]

     flushout    Flush the output queue for the device.  This is most
                 useful when an exiting processs is stuck waiting for
                 terminal output to drain.

    Could we get that for FreeBSD?
