+1 on consolidation here of completely unrelated tests. If we find that the interaction of such tests cost us much in terms of lost signal or unexpected cross-module interaction we can separate them in the future. Our integration tests are expensive to setup and to run as far as time. so it's good to be as broad as possible with our tests.

instance launch. Generally tests should only be added here if a failure
of the test would be unlikely to affect the running of another test using
the same instance launch. Most independent module coherence tests can go
here.
