I don't know what Augustin's reason is, but we (furfly) sometimes see a situation where one nsd thread is consuming a lot of CPU cycles while the others appear to be fine. It would be nice if one could just kill off that thread without having to restart, since it takes a minute or two for the site to come back up. I've been tempted to do this many times but I never have; it just seems like A Bad Idea (tm).
