The issue only seems to occur when I'm running the buildworld within a terminal in Xorg. I think it may be a contention issue with the 'nvidia' driver since during certain phases of the buildworld I often see top saying something's waiting on a lock - and I've spotted nvidia0 waiting on Giant a few times. I'll test using the nv driver instead and see if the problem still occurs. -- Bruce -- Bruce
