You probably ought to specify exactly what the task you're trying to accomplish is. While I could read the code and guess what the exact task is, guessing is unsatisfying. Also, if you rely on the code to be the specification, then obviously the code you provided is the best code that satisfies the requirements. Since we can't see the actual requirements, we can't differentiate between bugs and shortcomings from actual customer requirements.
