 * @assertion Future<FileSystem> requestFileSystem(int size, {bool persistent: false})
 * Access a sandboxed file system of the specified size. If persistent is true,
 * the application will request permission from the user to create lasting storage.
 * This storage cannot be freed without the user's permission.
 * Returns a Future whose value stores a reference to the sandboxed file system for use.
 * Because the file system is sandboxed, applications cannot access file systems created
 * in other web pages.
 * @description Checks that FileSystem is not accessible outside its web-page.
 * todo is it in other page?
