Oops, I found the same pattern on i386 - and that made me think about it
again: All fine, red herring, no bug.

What I failed to see is the special case of switching from the
gatekeeper back to the Xenomai thread that is about to be hardened. In
that case, we actually do not see the second pid trace after the switch.

Ok, the world was just proven to be still round. :)
