You can do this at will. As soon as you want to pause
time, it actually does that. But since this will also
pause your mental processes together with everything
else, neither you nor anyone else will ever notice! It's
just you who can do this Kyle, and noone ever notices...
What does this have to do with Python? ;)

Why is this better than "time.sleep(60)" ?

Can you explain a little more what you are trying to achieve?

If you write a GUI program, there will be special
close events that you can bind to a function. I'm
not sure I fully understand your question though.

There is also some general hook for exiting python
programs... Hm... Check the library reference for
sys.exitfunc() and the atexit module.

I don't think there is anything you can do to save
things when the program is being shot down with a
signal though. For a non-gui program I think this
is what happens on computer shutdown.

Or do you just want to stop your program? You have
to explain better...
