Are you using NPTL or Linuxthreads ? Could you tell us in what state the
switchtest threads are when running ps and in /proc/xenomai/sched ?
After the second Ctrl-C, are the threads still alive ?

Since after the first Ctrl-C, CPU 0 switches are no longer displayed,
the program probably started the cleanup correctly; if gdb does not
tell you where the main thread is blocked, could you try adding some
printfs in the main thread ?
