    truss - Fail properly, if we suddenly are missing permissions.
    
    * This avoids infinitely retrying the ioctl in a loop. If we are missing
      permissions, it's reasonable to just give up.
    
    * This happens for example, when you try to run truss on a setuid executable
      like ping(8).
