This function must return 1 by stateful objects to keep being called by STATE_D. If they do not, they're removed from
the queue. If they do, they're added to the queue again by STATE_D and set to be called after query_call_interval()
minutes has passed.
The *extra* is the argument parsed to STATE_D when registered.
