I think David (Mosberger, not Miller :) is right here, and in fact
this is also wrong on PPC at the moment. 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.
