Its only purpose is to a) identify a special kind of objects who usually having a weak references but also having an instance of me held by first non-weak fixed slot (instance variable). b) a 'first' instance variable points to the head of a list of items, reported by VM which has weak references which became garbage during last garbage collection At my class side, there are some public behavior, which is used by finalization process to detect if VM supports new finalization scheme or should use the old one.
