Up to now, we've only worried about whether tests running in parallel within a single test suite can interact. It's quite scary to think that the meson setup has expanded the possibility of interactions to our entire source tree. Maybe that was a bad idea and we should fix the meson infrastructure to not do that. I fear that otherwise, we'll get bit regularly by very-low-probability bugs of this kind.
I don't think there is anything fundamentally different in the parallelism setups of the make-based and the meson-based tests. There are just different implementation details that might affect the likely orderings and groupings.
