- *   - converted into a loadable module
- *   - NAWS support / ioctls for querying/setting the window
- *     size added.
- *   - don't delete the running task when the connection
- *     is closed. Rather let 'read()' return a 0 count so
- *     they may cleanup. Some magic hack works around termios
- *     limitation.
