No problem, help is always appreciated. And it's easy to get confused
when there is no documentation available on a feature.

Great ! :)

BTW, have you tried the user-space tracer library currently in
development: UST ? It's a port of LTTng to user-space.

It would be good to give it a bit more exposure, since we plan to

Feedback is very welcome, (so are patches) ;)
