-void Shutdown() {
-  // TODO: Move this out to a separate doc.
-  // On shutdown, it is nice to quit all running sessions so that we don't
-  // have leftover Chrome processes and temporary user data dirs.
-  // To do this, we execute the quitAll command.
-  // Alternative shutdown behaviors:
-  // 1. If the user doesn't quit the session, don't clean it up.
-  //    This is what the FF driver does, except the temp dir is
-  //    cleaned up in FF because the client side is responsible for creating
-  //    the temp directory, not the driver.
-  // 2. Separate helper process that we spawn that is in charge of
-  //    launching processes and creating temporary files. This process
-  //    communicates to the helper via a socket. The helper process
-  //    kills all processes and deletes temp files if it sees the parent
-  //    die and then exits itself. This is more complicated, but it guarantees
-  //    that the processes and temp dirs are cleaned up, even if this process
-  //    exits abnormally.
-  // 3. Add Chrome command-line switch for socket/pipe that Chrome listens
-  //    to and exits if the pipe is closed. This is how the old
-  //    TestingAutomationProvider worked. However, this doesn't clean up
-  //    temp directories, unless we make Chrome clean its own directory too.
-  //    If Chrome crashes the directory would be leaked.
