That makes sense, but on the other hand hardclock seems unlikely to be delayed by much. The only thing that can block hardclock is another hardclock, an splclock, or an splhigh. And, maybe, splstatclock. I'm talking about -stable here, which is where I'm doing my experiments. John -- John Polstra John D. Polstra & Co., Inc.
