However, the worst case is that the reschedule or signal delivery will get delayed until the next interrupt on that cpu (max 1/HZ seconds). Since it is a pretty narrow window for the race I think it would be hard to observe the effect of the bug. I understand now, thanks. I've fixed up sparc64. So it's a latency problem, not a correctness problem.
