You can atry to use the Python function sys.getrefcount. Print the 
refcount of the parameter values before and after your extension gets 
called and print the refcount of the return value (s). I once forgot to 
increment the refcount of the None object which was put into the return 
tuple.

If you pass a list as a parameter, you should also print the refcounts 
of the list elements etc.
