   I don't think there's a way to write a proper test here without changing a bunch of things in the bus and queue code to expose internal hooks... and I don't think that's desirable.
   
   I guess the current test is good enough as an attempt to test this.
   
   But Jenkins seems to be hosed, so running the tests here will probably have to wait until after the holidays...
