    cap cpu_util

    deriving cpu_util from cputime is not exact as it relies on timing
    of host and a completely independent timing of pollster. this can
    cause precision issues with nanosecond timing resulting in >100%
    calculations. this sets a cap so at most cpu_util can only report
    100% cpu utilisation.
