Do not trust stdio printouts for debugging in a dual kernel system, they 
may be delayed in different ways, despite your termios are set to 
canonical mode.

In addition, testing return codes of syscalls would be a good idea, e.g. 
rt_task_start(), assuming rt_task_create() did succeed since GDB told 
you about two new threads.

PS: please keep the list posted.
