In Response To: GNU Gurus Enter Here (Stick)

Way off from the original here.

Thoughts?

I'm pretty sure my rollout is closer to the truth than the one Stick posted, but it still raises the question of why on Earth that should be.

David Levy suggested that it might be problems with GNU multithreading. That strikes me as at least as plausible as anything else at this point.

With Jacoby:
