Review Comment:
> To make it consistent, you need to synchronize in the metrics object and
set ALL the metrics in a single synchronized call.
Will do. At least try to keep possible inconsistency to a minimum. We
won't report metrics that show one value in one sample, that clear, then go
back to value due to our sampling from the monitor.
