I'm not claiming its perfect, but I am reasonably confident that I've
ironed out the major problems.
CTS does a pretty good job of exercising fencing.

Lars and I had a conversation about this a while back, he asked
questions, I gave honest answers.

But you have QA people right? And presumably a few betas before you
release SP1 right? And you've been testing it already right?
So what's the problem?  If its falling in a heap, you guys are being
mighty quiet about it.

Besides, this is what enterprise distros are all about, taking
upstream code and polishing it until its ready for paying customers.
They pay for the reassurance that it hasn't just been tested by the
idiot that wrote it.
