    probably not the only problem - but if we are lucky then his system was
    just trashing within the kernel repository and then most of the overhead
    is the _unnecessary_ IO that happened due to that (which causes CPU
    overhead just as much). The dominant system time suggests so, to a
    certain degree. Maybe this is wishful thinking.
