/**
 * @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 accessible from its web-page, and a
 * File can be created.
