Hi, it's been a while since I had a serious look into libgomp...

And, as far as I can tell, that seems to be the function gomp_thread_start. At the moment I cannot quite tell if the end of the function would be a good place for the thread termination event - or rather if it is sufficient and there may be others, I would need to dig deeper. But perhaps this already help? Martin
