GLSL GPGPU demo - with a crash. Please help?

Hi,

this could be a good demo + test for GLSL, and basic GPGPU processing with GLSL.

http://rene.f0o.com/~rene/stuff/gpudemo.py

1. basic glsl usage.
2. basic GPGPU style usage.


1. It requires opengl-ctypes latest cvs.  It works correctly with the command:

python gpudemo.py basic

That just shows a tea pot using a basic shader.



2. To run the GPGPU demo call it like this:
python gpudemo.py


This works correctly almost.   It crashes on program exit... The
results printed out are correct.  It appears to be a reference
counting type problem.

I've tried it on OSX with an ATI card.


So if people can test this, and debug it I'll clean it up and add it
as a nice demo for pyopengl.  I think it must have something to do
with the array handling... or something :)


cu,
