easier to do time.sleep(60)  ;-)  From the docstring:

>>> print time.sleep.__doc__
sleep(seconds)

Delay execution for a given number of seconds.  The argument may be
a floating point number for subsecond precision.

Marc Andre Lemburg speaks to this here:

The doc string from the post says:
    Singleton that manages exit functions. These function will be
    called upon system exit in reverse order of their registering.

So it sounds like you could (once could have?) queued up a number of
clean-up tasks to be performed before exitting.

HTH,
