  I would think it is good. I believe the necessary actions (card
marking) are taken with -XX:-ReduceInitialCardMarks from the comments,
in the places I would expect them. However my C2-fu is limited to
hacking together barriers, so I am honestly unable to verify that the
code in detail is correct.

Somebody more knowledgable in C2 in general needs to look at this.

If you have time, copyrights may need to be fixed up. I do not need a
re-review for that.
