I'd just like to confirm a few things. In my application my classes don't don't have to call waitForSignal and the join will still wait for all forks to come together before carrying on? And would I be correct in saying that it is therefore not possible to test async nodes in a fork realistically? i.e. There is no way to start two nodes at the same time in a unit test?
