Description
G1RedirtyCardsQueue currently contains a local qset for gathering the buffers generated by the current thread, reducing contention on the singleton global qset (JDK-8162929). Having the queue contain a local qset was chosen over having a separate local qset to simplify usage, at the expense of a bit more implementation complexity. However, in the interest of simplifying the PtrQueue hiearchy it would be better to separate them.
