   3 ! 2.15.2 threadprivate Directive
   4 ! The threadprivate directive specifies that variables are replicated,
   5 ! with each thread having its own copy. When threadprivate variables are
   6 ! referenced in the OpenMP region, we know they are already private to
   7 ! their threads, so no new symbol needs to be created.
