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. Paul Reitsma
