 //     compensating for the missing pre-barrier here. Turning now
 //     to the post-barrier, we note that G1 needs a RS update barrier
 //     which simply enqueues a (sequence of) dirty cards which may
 //     optionally be refined by the concurrent update threads. Note

-//     (much like CMS' precleaning), must strictly follow the oop-store.

-//     invariants turns out, serendepitously, to be the same for both
-//     G1 and CMS.
