-// SpawnerCommunicator communicates with a spawner server that runs on a
-// remote system.
-//
-// The test server used by unit tests is written in Python. However, Android
-// does not support running Python code, so the test server cannot run on the
-// same device running unit tests.
-//
-// The actual test server is executed on the host machine, while the unit tests
-// themselves continue running on the device. To control the test server on the
-// host machine, a second HTTP server is started, the spawner server, which
-// controls the life cycle of remote test servers. Calls to start/kill the
-// net::SpawnedTestServer are then redirected to the spawner server via
-// this spawner communicator.
-//
-// Currently only three commands are supported by spawner.
-//
-// (1) Start Python test server, format is:
-// Path: "/start".
-// Method: "POST".
-// Data to server: all arguments needed to launch the Python test server, in
-//   JSON format.
-// Data from server: a JSON dict includes the following two field if success,
-//   "port": the port the Python test server actually listen on that.
-//   "message": must be "started".
-//
-// (2) Kill Python test server, format is:
-// Path: "/kill".
-// Method: "GET".
-// Data to server: None.
-// Data from server: String "killed" returned if success.
-//
-// (3) Ping Python test server to see whether it is alive, format is:
-// Path: "/ping".
-// Method: "GET".
-// Data to server: None.
-// Data from server: String "ready" returned if success.
-//
-// The internal I/O thread is required by net stack to perform net I/O.
-// The Start/StopServer methods block the caller thread until result is
-// fetched from spawner server or timed-out.
