[vtkusers] unfreed memory?

[Luca Picello]

You're absolutely right!!!
in this example I forgot to call

sphere0->Delete();  // delete source if we no longer need it
and
sphereMapper0->Delete(); //delete mapper since actor has referenced it  

And now it seems the memory is right deallocated.
Sorry for the mistake...
