You know how BSD advocacy folks like to tell you they "don't like politics"? It's kind of like the story in the Onion about that guy who keeps telling people he doesn't own a television and how much more fulfilling his life is, even when no one asked.

The "patch" which is available for FreeBSD to fix this problem only disables hyperthreading and does not provide a real fix.
