My cpu or mothboard (Intel P133 and ASUS P/I-P55T2P4) gives off weird
EMI pulses when FreeBSD idles the cpu.  Anything from a while(1) to
xmountains fixes this.

Thus, my question:  is there any way to make a process so that it gets
NO cpu time unless NO other processes want the cpu?

(I've tried using nice w/min priority, but there's still a very
noticeable performance hit).

(of course, finding a way to shut the EMI off would work, too...)


Thanks in advance.
