Problem: Python test server not displaying second of two commands.
Solaris doesn't have "pkill --full".
Solution: Also echo the second command. Use "pkill -f".
Problem: Crash when the process a channel is connected to exits.
Solution: Use the file descriptor properly. Add a test. (Damien)
Also add a test for eval().
Problem: Can't reliably stop the channel test server. Can't start the
server if the python file is not executable.
Solution: Use "pkill" instead of "killall". Run the python file as an
argument instead of as an executable.
