/// @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,
/// and a Directory can be created.
/// todo is it in other page?
