This check is clearly incorrect, there's no way you should have an eStateConnected event left on the queue if you've already launched and hit a breakpoint in the program. This check fails running remotely on Darwin systems and on one remote Linux platform. And if we do find this failing somewhere, we should fix the bogus eStateConnected, not the test.
