Objects that do define a Finalize method are placed on the freachable (pronounced F-Reachable) queue. A dedicated thread responsible for calling Finalize methods sleeps when no objects are in the freachable queue. When objects are added to the queue, the thread is awakened and calls the Finalize method.
