There was a subtle bug that realizes exactly what you explained, thank you! 
Question is: after a successful rt_task_shadow() call done by a pthread, we can forget that this rt-task 
was created as pthread and then we must handle it with rt_task_* procedures, is it right? 
In other words, does pthread become a RT_TASK at all, as if it was created with rt_task_create()? 

Thanks again, Gilles.
