No need > to use poll() in our little programm I sent previously. And this is a lot more strange ! If we start the gettimeofday() loop once (on one CPU) I get the timedrift with 8 seconds per minute. If we start it twice so it runs on both CPU's, there is no significant timedrift !!! Something here is cracy.
