Well, setting up all that polling and messaging between slave_pack.py and the signing machine is what then needs to be set up and tested. With the buildbot we have already something that is tested and working with certainty, without having to write custom code that can fail.

@Jeroen Bakker (jbakker) I remembered having dealt with something like this when I had the Intel CPU OpenCL driver installed as well - it has been a few years since I tested that, and opted to remove that driver, since it caused a whole lot of instabilities on my machine. Perhaps something to keep in mind while investigating.

I think best is to update https://developer.blender.org/diffusion/B/browse/master/build_files/build_environment/patches/opencollada.diff with any patch we deem necessary to keep things rolling. This seems to be the way we have quite a few patches to ensure different libraries compile well for Blender.

IIRC the double enumeration occurs because of two different OpenCL platforms being available - one from AMD, one from Intel. I have found the Intel platform for OpenCL to be quite unreliable - I think I've blacklisted it for Cycles in Rhino so that one can not select it.
