    daemonize: Ensure child process exits safely
    
    When we create the child, if an exception occurred it was transfering
    back into the parent context. We don't want to do that us use a try/finally
    to ensure we exit.
    
    We need to ensure a traceback is printed and any queued UI messages which
    may not have made it to the client UI at this point.
