I think this is a good way to go about it. However, if it's likely that separate invocations of this program will occur, a random filename would be a Good Thing.

There's also the tried and true trick of writing a sentinal file that other programs check for and then seeking to the beginning of the original file and truncating it, but renaming seems much easier.
