Are you talking about what he's saying at approx. minute 36?  That's the
closest thing I could find to what you're claiming he said, but he's
talking there about why they didn't release OpenSolaris under the GPL.
He's not saying anything about whether or not the CDDL is incompatible
with the GPL.

Actually, what he's saying is that the different threading model
prevents you from cut-and-pasting code.  He's saying that in order to
port DTrace to Linux, due to the different architecture, you would have
to basically rewrite it, and so the CDDL would not cause any problems in
that case, since you are rewriting, and would not be creating a
derivative work.

What he's saying is that the technical problems are bigger than the
legal problems, and that the most sane way to get around the technical
problems are to do so in such a way that the legal problems no longer
apply.  He is not saying that there are no legal issues.

He's specifically talking about the so-called "operating system
exception" in the GPL v2, and what the GPL v3 refers to as "System
Libraries".  He's not talking about any random library.
