Good point. This could be handled by the serializer maintaining a WeakHashMap of the sessions that use a particular bundle and blocking in the bundle activator's stop method until the list is empty.
But if a user was busy for an extended period, like some kind of automated scraper or monitor that ended up having the session open for days, the check would have to be more granular than the session. Which seems like it's going to be different between 1.4 and 1.5 because of the migration from pagemaps.
