Publicly, I'll state that I don't think that devstat is the right place = for these, and I was hoping to have some time to move them to a better = place, or at least fix up the existing problems that are present. This = commit shouldn't be considered the final word the stability of this set = of SDT probes. Scott On Dec 7, 2012, at 12:06 PM, George V.
