    13 System time has improved yet again, while overall time for this task takes almost 5 seconds more since the initial merge. I am not even sure the observation that it has mainly to do with thread migration is even correct. That would mean that there should be one or two cores that are peaked during an interval, while others have nothing to do. But all my four cores have mostly nothing to do while the compile runs. Activity Monitor reports loads as low as 17 % during a half-second average for a core, and most cores don't go beyond 70% load.
