// This WebUI page displays the status of the renderer sandbox on Linux and
// Android. The two OSes share the same basic page, but the data reported are
// obtained from different places:
//    - On Linux, this object in the browser queries the renderer ZygoteHost
//      to get the sandbox status of the renderers. The data are then specified
//      as loadTimeData on the WebUI Page.
//    - On Android, this object sends an IPC message to the
//      SandboxStatusExtension in the renderer, which installs a JavaScript
//      function on the web page to return the current sandbox status.
