There is no generators JEP on the table at the moment so this entire discussion is up in the air, but the generator signals completion by simply terminating (recall the Continuation.isDone() method that queries whether the continuation is terminated or suspended). The consumer signals completion by simply not consuming any more elements. When the reference to the generator is dropped it can be collected (this is how it works for iterators and streams, too).
