Okay this is weird. G is showing about 3 forum.example.com urls -- despite the forum subdomain being deleted in 2006, and all non www. urls 301'd to www. (apache rewrite rule).
I've also noticed that there's a good 50 or so URLs in the dupe index that have been returning 404s for over 12 months... this is frustrating.
