I seem to understand the problem(s). I am a bit surprized. Basically I have the questions about almost every utrace_ function. I'll try to recheck and summarize my concerns tomorrow with a fresh head, I hope I missed something. And I think at least we should cleanup utrace_set_events(), I'll try to send the patch a bit later. Oleg.
