- g1CollectedHeap.cpp:3754, active_workers should be a uint I think to
match the parameter types.

- minor style issue (feel free to ignore): the change stores the
G1GCPhaseTimes instances into local variables a few times. That variable
is sometimes called "timer", "phase_times". Also e.g. G1CLDClosure may
benefit from introducing a local variable.

- another (feel free to ignore): in the long sum starting with
g1CollectorPolicy.cpp:1134 the operators are sometimes at the end of the
preceding line, sometimes before. I would prefer them at the end of the
preceding line.

- thanks for removing the PRAGMA's in g1GCPhaseTimes.cpp. :)

Looks good otherwise.

Thanks,
  Thomas
