Hi all,
can I have reviews for this change that updates the gc,liveness output to add the remembered set state?
This change adds a column next to "remset" called "state" that can be either UNTRA (Untracked), UPDAT (Updating) and CMPLT (Complete).
There is a log snippet attached that shows the new output.
If somebody asks, I kind of agree that we should probably rethink this output (remove some of the addresses, add region number), but this is imho out of scope for this change. ;]

Thanks, Thomas
