You are missing the trailing parentheses here:

        tmpfile.close


By leaving out the parentheses, you're not calling close; you've just
created a callable expression that doesn't do anything. As a result, when
you move the file, there is a race condition. The contents of the new file
may still be in buffers and not actually written to the file yet when you
call the move routine.
