Andy, John,
Thanks for looking into this and all the input. After a bit of looking
around I gave up trying to track down the real cause of the
leaks. Instead, I modified my coprpcessing Python script not to
recreate and delete the pipeline objects each time DoCoProcessing() is
called (attached slices.py) but to re-use them (attached slices2.py,
you might try diff -bu slices.py slices2.py).
As can be seen from the respective profiling results slices.png and
slices2.png, no noticeable leak is observed for slices2.py. This is
not a fundamental solution but could be a workaround for the moment.

Basicaly I kept a counter in vtkObject that incremented for each constructor call and decremented for each destructor call. At the end of every call I had the same amount of vtkObjects.

While there was some memory leaks reported, the amount didn't increase with the number of times the coprocessing pipeline was executed. Curiously though, valgrind did list an increase in the amount of memory that was leaked. It seemed like there were quite a few PyObjects that weren't getting deleted properly though and maybe getting rid of them properly would help. It may also be that memory fragmentation is a problem since rather large arrays are probably being allocated to for the field data as well as the opengl arrays (turning on immediate mode rendering would help with that but I'm not sure how to do that through the python but maybe someone else does).

I'll keep looking but it's possible that you're not deleting your created data object that is getting passed into the coprocessing library. That would be my first recommendation to check. You may want to turn on debug leaks if you haven't in your paraview build.
