[Paraview] Excessive memory consumption when loading a series of VTK legacy files

[Utkarsh Ayachit]

Hello Roman,

Thanks for raising this issue. There was a bug in the client code during 
constructing the Undo-Redo stack for creation of the reader. This issue 
has now been fixed on the CVS head and will soon be added to the 3.2 
branch. It will be included in the 3.2 stable release.

Thanks,
Utkarsh
