It's possible that one of the paraview python modules, like paraview.simple
or paraview.servermanager, is maintaining a dictionary or some structure
that is growing without being cleared, does not contain vtkObjects, and is
cleared at shutdown so does not show up as a leak.
Also, Takuya's solution of not re-creating the proxies each call to
DoCoProcessing is a desirable feature. In the past, I have done strong
scaling runs where the setup & teardown that takes place in each call to
DoCoProcessing takes longer than the filter execution. I'd love to see the
coprocessor have formal support for Takuya's solution (still, it will be
nice to track down the cause of this memory growth...)
