Matt, Thanks for the great explanation! Hopefully, I'll get a chance to try this for alpha (though I won't mind if somebody beats me to it). I've also been meaning to get iprobe (kernel profiler) going again too, to find out why -current on alpha sucks so badly right now. (your gettimeofday() syscall test shows that -current has over 2x the overhead for syscalls on alpha, even w/o INVARIANTS).
