It maintains all the rdb$db_key values for the length of a connection - i.e. they are not allowed to change. An internal transaction gets started for this. It was introduced to support Cognos' Powerhouse 4GL product which made extensive use of db_keys. Obviously it can have issues re. garbage collection...
