Seguridad para subprocesos

Todos los miembros de este tipo son seguros para subprocesos. Los miembros que parecen modificar el estado de instancia devuelven realmente una nueva instancia inicializada con el nuevo valor. Al igual que con cualquier otro tipo, leer y escribir en una variable compartida que contenga una instancia de este tipo debe estar protegida por un bloqueo para garantizar la seguridad de los subprocesos.
