SUJ progress report

Hi Folks,

Kirk, Peter and I have been working hard on SUJ.  We still have a few bugs 
related to snapshots but we fixed the couple of potential corruption 
problems that came up over the last year.  If you are not currently using 
SUJ I implore you to do so and report any problems you may find..  We need 
to get better coverage if we are going to enable it for 9.0 which I think 
everyone would like to see.

I will send another update when it is safe to use SUJ + snapshots.

Thanks,
Jeff
