Excerpts from Brandon Simmons's message of 2014-05-10 13:57:40 -0700:
Another silly question: when card-marking happens after a write or CAS, does that indicate "this segment maybe contains old-to-new generation references, so be sure to preserve (scavenge?) them from collection "? In my initial question I was thinking of the cards as indicating "here be garbage" (e.g. a previous overwritten array value), but I think I had the wrong idea about how copying GC works generally (shouldn't it really be called Non-Garbage Preservation?).
That's correct. Cheers, Edward
