It's not just you. Over the last couple of weeks the googlebot has revisited-- that is, requested-- every page I have ever 410'd. Explicit 410, not just 404. That means: pages that for months and months were requested by absolutely nobody except the bingbot (which doesn't seem to grasp the 410 concept*).
* Possibly because they know that if they keep bugging me, I will eventually knuckle under and feed them a few more handcrafted 301s :(
