Use try/finally if the task is clearer that way. atexit is better
suited to libraries. logging uses atexit (flushing/closing handlers)
as does multiprocessing (terminating/joining active child processes).

As to the risk, atexit was added in 2.0 and directly using
sys.exitfunc was deprecated in 2.4.
