It is essentially mutilple interrupt support. So when you install an
interrupt it creates "a chain" to whatever interrupts are currently
installed. You can install a grayscale interrupt handler and then
install a sound interrupt handler. They are in essence "chained"
together, as one is called right after the other when an interrupt
occurs.
