As a warning: GVNSink is non-deterministic, which makes it easy for tests written in one environment to fail on some buildbots. I don't know whether it will affect this specific test. This non-determinism (and the fact that it prevents us from writing tests) has been blocking various fixing in this incredibly broken pass.
