 /**
  * Wrapper for Inbox::stream() and Notice::getStreamByIds() returning
  * additional items up to the limit if we were short due to deleted
  * notices still being listed in the inbox.
  *
  * The fast path (when no items are deleted) should be just as fast; the
  * offset parameter is applied *before* lookups for maximum efficiency.
  *
  * This means offset-based paging may show duplicates, but similar behavior
  * already exists when new notices are posted between page views, so we
  * think people will be ok with this until id-based paging is introduced
  * to the user interface.
  *
  * @param int $user_id
  * @param int $offset skip past the most recent N notices (after since_id checks)
  * @param int $limit
  * @param mixed $since_id return only notices after but not including this id
  * @param mixed $max_id return only notices up to and including this id
  * @param mixed $own ignored?
  * @return array of Notice objects
  *
  * @todo consider repacking the inbox when this happens?
  * @fixme reimplement $own if we need it?
