Perhaps try the sys.exitfunc or atexit modules:
exitfunc
This value is not actually defined by the module, but can be set by the user
(or by a program) to specify a clean-up action at program exit. When set, it
should be a parameterless function. This function will be called when the
interpreter exits. Only one function may be installed in this way; to allow
multiple functions which will be called at termination, use the atexit
module. Note: The exit function is not called when the program is killed by
a signal, when a Python fatal internal error is detected, or when os._exit()
is called.
Deprecated since release 2.4. Use atexit instead.

Hope it helps,
