I don't see whatever message you were replying to, and it doesn't seem to be archived in lore[1], so I'm not sure about the context. But you are talking about the Dhrystone benchmark[2], right?

If so, I'm confused what you mean by "add enough glue so that it would be runnable from userspace" --- Dhrystone is a userspace benchmark, dating from the 1980's, although what it benchmarks is often more about the compiler than the CPU's performace.
"When first released, the Dhrystone benchmark fulfilled a useful function – at least it gave an alternative indicator to vendors’ literal MIPS ratings. However, more than twenty years later, there are undoubtedly better benchmarks available for measuring processor performance."
