 The :mod:`atexit` module defines functions to register and unregister cleanup
 functions.  Functions thus registered are automatically executed upon normal
-interpreter termination.  The order in which the functions are called is not
-defined; if you have cleanup operations that depend on each other, you should
-wrap them in a function and register that one.  This keeps :mod:`atexit` simple.
+interpreter termination.  :mod:`atexit` runs these functions in the *reverse*
+order in which they were registered; if you register ``A``, ``B``, and ``C``,
+at interpreter termination time they will be run in the order ``C``, ``B``,
+``A``.
 
-Note: the functions registered via this module are not called when the program
-is killed by a signal not handled by Python, when a Python fatal internal error
-is detected, or when :func:`os._exit` is called.
