  11 Description:
  12   Before setting a nested lock, the lock variable must be initialized by
  13   ``omp_init_nest_lock``.  The calling thread is blocked until the lock
  14   is available.  If the lock is already held by the current thread, the
  15   nesting count for the lock is incremented.
