  Log:
  Fix information leakage.
  Without this fix it is possible to cheat policies like:
  - sysctl security.bsd.see_other_[gu]ids=0,
  - mac_seeotheruids(4),
  - jail(2)
  and get full processes list with their arguments.
  
  This problem exists from revision 1.62 of kern_proc.c when it was
  introduced.
