The main problem remains for the moment since Pharo's default download includes not this VM but the itimer one. I talked with Esteban about it and he was aware of these two VM flavours, and the reason why we are using the itimer one is the need to deploy those permission files in /etc, which makes installation a bit less automatic.

It is not a matter of configuration, e.g. more infrastructure is migrated into docker containers (I run the CI with docker containers) and even as root inside the container you might not be allowed to use realtime priority. And you might not be able to influence how your container is being executed.


PS: Have you seen the fix David Lewis made to the UnixProcess plugin, maybe it already helps with your bug as well?
