I am writing a command line application, and I need to perform some

python?
Write an “exit handler” function, then use ‘atexit.register’
<URL:http://docs.python.org/library/atexit> to register yours for
processing whenever the program exits.
Unfortunately neither sys.exitfunc nor function registered with
atexit.register() are called when process is killed with signal.
As I wrote, you must use signals. Though sometimes it's a good idea
to combine these two techniques (i.e. signal handlers call sys.exit(),
then sys.exitfunc/or function registered with atexit does the actual
cleaning actions).
