Ah, sorry, I wasn't being precise. I meant the python commandline
python interpreter.

So from a terminal I type (for example):
python -i application.py

This launches the interpreter in my terminal. Then I can start the GUI
(by typing "Application()", for example). If I use mainloop(), I can't
interact with the interpreter from the terminal until I quit the GUI.
Without mainloop(), I can continue to enter python commands.
