I agree with Dugger. Orphaned or not, backlinks or not, once Google gets a url to resolve even once, then they will keep checking on it for years and years - although with declining frequency. There is nothing to worry about here. And sometimes, you can get some happy results by recycling the flotsam and jetsam you find this way.
