RequestUserInventory is supposed to drive a supplied callback when it completes. In fact, it fails to do so if the user's inventory does not exist (e.g. the inventory database is unavailable for some reason), and the requestor is left sleeping forever. The code has been modified to return empty lists via the callback as an accurate reflection of what is there: nothing.
