  Log:
  SVN rev 215661 on 2010-11-22 08:21:58Z by netchild
  
  MFC r215338:
    - print out the PID and program name of the program trying to use an
      unsupported futex operation
    - for those futex operations which are known to be not supported,
      print out which futex operation it is
    - shortcut the error return of the unsupported FUTEX_CLOCK_REALTIME in
      some cases:
        FUTEX_CLOCK_REALTIME can be used to tell linux to use
        CLOCK_REALTIME instead of CLOCK_MONOTONIC. FUTEX_CLOCK_REALTIME
        however must only be set, if either FUTEX_WAIT_BITSET or
        FUTEX_WAIT_REQUEUE_PI are set too. If that's not the case
        we can die with ENOSYS right at the beginning.
