    Will this DPS-like thread allow you to turn of such things as IO-apic
    interrupts and reroute all interrupts to the processors that is not
    running the real time thread?

    I have _hacks_ that do this and it works quite nicely but it would be
    nice
    to find som more general API for this type of functionality. I do not
    have
    the time to do that.

    If your goal is at the "5 ms level" then interrupts may not matter to
    you.
    Is this the case?
