I think this is a good example. difflib.SequenceMatcher is linear to
quadratic (says Tim) in the number of items and can take seconds or
longer in real-life-sized use cases. It is all indexing, comparison,
looping, and logic, so I think it would be an interesting test case.
There is no C version now, so a sped-up version could be immediately
useful to some people.
