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.
