                  that you can specify 0 as a device_port, in which case a
                  port will by dynamically assigned on the device. You can

       tool: Tool class to use to get wrapper, if necessary, for executing the
             forwarder (see valgrind_tools.py).
-      host_name: Address to forward to, must be addressable from the
-                 host machine. Usually use loopback '127.0.0.1'.
