* Pass in Destination lazily in startFlowing instead of createRequest * Delay fatal errors until we have a destination to forward them to * Flow can now be inferred by whether there's a destination set We can drop the destination when we're not flowing since there's nothing to write to. Fatal errors now close once flowing starts back up again. * Defer fatal errors in Flight too
