Per the buildfarm, these tests appear to be unstable in the wake of commit ddb17e387aa28d61521227377b00f997756b8a27. I'm not sure that just hiding this output is the right way forward, because I think there may be other test cases that will fail with lower probability even after this fix. However, it's hard to tell right now, because this is failing on a number of buildfarm animals. So let's try this for now to either get a clearer picture of what else is broken, or as a stopgap until we decide what the permanent fix should be, or perhaps this will be the permanent fix after all.
