    Subject: [PATCH] Adds flushing of stdout and stderr after writes
    
    Because output is written without ever closing the fds until sys.exit is
    called after a `KeyboardInterrupt` exception, it is difficult to read
    stdin or stdout from a parent process that may spawn a development
    server subprocess.
