Thanks for fixing this patchset up and sending out a v2.  I took a closer look 
and just sent out my comments, let me know if you have any questions.

Once we get to a v3 patchset, I think it's time to reach out Oracle and try 
some interop with Solaris TX.  Let me know when you are ready and I'll put 
everybody in touch to try to get some testing going.
