We associate stats with tabs to allow the Twitter share button to work in the popup menu. Unfortunately, (a) these values stick around at the end of the session, which could waste a little bit of disk space; (b) they're not overwritten (!), so pages with no scores may turn out to have linked-stats from a long-dead tab, and an activated Twitter button that could cause a bogus tweet to be published if the user doesn't check first.
