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.
