That's good to hear! I was thinking about giving OpenMP a try in my package, but am not sure whether it's worth the overhead and risk of compatibility problems. Are there any plans to expand dist() to calculate "cross-distances" between two different sets of vectors? If so, I'd be able to do away with my custom implementation once your improved dist() has made it into a stable R release. (I need cross-distances for nearest neighbour search in large sets of vectors.)
