[Paraview] pvpython eating all my memory

[Berk Geveci]

Hi Peter,

First of all, I apologize for taking so long looking into this.

I think I know what the problem is. In prog_filter.py, you are doing
the following:

outputBlock = inputBlock.NewInstance()

Due to some issues in VTK's reference counting and the way it
interacts with Python, this causes a memory leak and outputBlock is
never released. Try this:

outputBlock = inputBlock.NewInstance()
outputBlock.UnRegister(None)

instead. I bet you this will fix the memory problem. I will
investigate how we can solve this problem in VTK in the future.
