I made a few attempts, but didn't have any luck and decided to post these patches based on the other evidence I'd gathered. I agree that I would much prefer understanding who is doing this, even if it doesn't change the workaround method. > It should be possible to do so using > systemtap without all that much trouble. My full experience with systemtap is using some of the examples from your blog posting on the topic :-)

I would love to figure this out, though. The complicating factor I can see (aside from me needing to learn how to write a systemtap script) is that in this case stap needs to be run on a daemonizing process, from the very beginning. If you can give me any better advice than "go read the systemtap website", please do.
