It might be valuable to run the application under "screen".
Screen will keep a pseudo terminal alive even if the current terminal
session is trashed.
Try
screen
vi /tmp/watchme
Kill the terminal session (click on the X in the upper right)
Start a new terminal session
screen -r
You might also use the gnome-terminal Menubar and reset the
terminal.
You might also keep track of the tty then see what the tty values
are over time.
stty -a < /dev/pts/3

May your cup runneth over with goodness and mercy
and may your buffers never overflow.
