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?
