I would like to merge this class and G1BuildCandidateRegionsTask in the near future because the latter mostly repeats the work of the former anyway, but together (with helper classes) they are quite large (if not large already by themselves). This should help make `g1ConcurrentMark.cpp` a little more manageable.
