  looks good. Some remaining minor issues:

- concurrentG1RefineThread.cpp:71: indentation

- the selected thresholds for the flags will cause overflows in the
calculations later, look for uses of
G1ConcRefinementServiceIntervalMillis, the *Zone values (e.g. in
g1CollectedHeap.cpp:1988f, g1CollectorPolicy.cpp:1323f,... I recommend
keeping max_intx at most.

Sorry for earlier comments to the opposite :(

I think this can be done without a re-review from my pov (unless more
issues pop up).

Thanks,
