An early G1 tester reported that 8% of the update buffers are being processed by mutator threads. It'd be nice if we could make sure that all of them were being processed by the concurrent refinement threads. And, while we are at it, we should make sure that we process update buffers as aggressively as possible by the concurrent refinement threads to minimize the amount of work we'll do during the pauses.
