[vtkusers] Recreating a smart pointer object after deletion

If I do this (which works fine (no crash)):

  vtkSmartPointer<vtkFloatArray> distances =
    vtkSmartPointer<vtkFloatArray>::New();
  std::cout << distances->GetNumberOfComponents() << std::endl;

  distances.TakeReference(vtkFloatArray::New());
  std::cout << distances->GetNumberOfComponents() << std::endl;

there is a leak, right? The first vtkFloatArray object is never
deleted. How do you delete the memory allocated to the first object?
(This is why I had tried calling Delete(), which you say should never
be done (and I agree, as it causes a crash every time :) )
