That is unnecessary and dangerous in Python. 98% of the time the Python interpreter cleans up what you would have had to clean up by hand in C. The rest of the time you should be using a try...finally block to guarantee cleanup, or a with block to get the interpreter do it for you. Calling a nested function to perform cleanup is prone to omission errors, and it doesn't guarantee that cleanup will happen if an exception is raised.
