    Agreed, Theo just yelled at me cause I was having this discussion on the
    OpenBSD misc mailing list, which is my fault :-/ ... a lot of people were
    responding though and I think it just got out of hand.

    As much as OpenBSD seems nice, my FreeBSD experience is a lot better. I'm
    going to switch to Uniprocessor and see if that makes us more stable.
    Hopefully it will.
