Ok. That seems a good plan.
I will be glad to help if I can when you have more details.
On a related note, I received a report that XenOprofile is missing some
user level samples. I am preparing a patch with the fix and should post
it to the list later today. This should affect kernel samples though.

No I don't know when 0.9.3 wil be out. I still need to sync up with
William Cohen to get the passive domain patches into the oprofile CVS
tree. I was waiting to finish some cleanups in the patch before sending
it to him, but I did not have had time to work on this yet.
