// Android log by the renderer process itself. However, the browser may need to
// crash itself on a renderer crash. Since on Android renderers are not child
// processes of the browser, it can't access the exit code. Instead, the browser
// uses a dedicated pipe in order to receive the information about the renderer
// crash status.
