Sorry for the delay getting back to you on this. I was just wondering 
about JvmtiTagMap::do_weak_oops and whether the delayed_add list could 
be avoided. Maybe not and I was just wondering about the cost of 
visiting objects that were re-hashed to higher slots. I guess it's an 
is_alive vs. iterating over the delay_add list to put the entries into 
the right place. The hashing code would be the same.
