Comment(by river_at_[hidden]):

 it does not:

  {{{

         __sync_lock_test_and_set(&i, 1);
         return 0;

  }}}

 (PA-RISC does provide a single atomic operation - 'load and clear word'
 (ldcw), which is roughly equivalent to `__sync_lock_test_and_set(&x, 1)`.
 Unfortunately, I'm not comfortable enough with the platform to provide an
 implementation.)
