SMP backend OpenMP: awkward destructor shows Clang compiler warning.
/src/vtk/Common/Core/SMP/OpenMP/vtkSMPThreadLocalBackend.h:89:29: warning: class with destructor marked
'final' cannot be inherited from [-Wfinal-dtor-non-final-class]
virtual ~ThreadSpecific() final;
This is not a breaking issue. It is just a bit awkward. What is the intent here? virtual and final are opposing each other's purpose..
