Corey,

sorry for delay -- I had to check some things. Yes, we plan to publish
our changes in near future. I should warn that at present, our
code is not entirely self-contained -- it uses some functionality
from our product. However, I imagine the patch would still be
useful as it does quite a few oprofile refactorings.

Thanks,
