Interesting! Is there a more detailed post about this?

I wonder how they decide which objects are rooted only by the stack. Is it part of the write barrier, or computed at mark time?

I think it just forces objects to survive more than one collection before moving out of the nursery, without having a special logic for whether they were rooted on the stack or not. But I am not 100% sure so don't quote me on that.
