[vtkusers] growing RAM memory

[G G]

When I use

        ren = NULL;
        ren = vtkSmartPointer<vtkRenderer>::New();
        ren->SetBackground(1,1,1);
        ren->AddActor(actor);
        widget->GetRenderWindow()->AddRenderer(ren);

it works but, memory is grown again.

when I use

        ren->Delete();
        ren = vtkSmartPointer<vtkRenderer>::New();
        ren->SetBackground(1,1,1);
        ren->AddActor(actor);
        widget->GetRenderWindow()->AddRenderer(ren);

it doesnt work.

I am desperate. :(
