This is a renmant of the original change that forced a full gc every iteration. This is not necessary, the object should be finalizable after the first full gc already. That is, the comment is wrong. However we might need to wait a bit until the finalizer actually executes. I updated the comment.

I did not try optimizing the maximum wait time.
