    this has been implemented in a clean way already: check out the
    "isolcpus=" boot option & scheduler feature (implemented by Dimitri
    Sivanich) which isolates a set of CPUs via sched-domains for precisely
    such purposes. The way to enter such a domain is via the affinity
    syscall - and balancing will leave such domains isolated.
