      Description

      G1RemSet::_conc_refine_cards, the number of cards actually refined after all filtering, is incremented in an unsynchronized fashion.

      This may lead to completely off values when multiple refinement threads are working on it.

      Note that this may be intentional, but if so document this behavior.
