How could I avoid garbage being left over?
Would that explain that the memory usage doesn't decrease?

Reference counts before and after calling delete:
actor: 1 to -1181117928
mapper: 2 to 74658944
polydata: 3 to 0

I create polydata then mapper then actor.
I delete actor, then mapper, then polydata...

Thanks for your help,


Nicolas
