If a user holds a button down on a remote, then no ir idle interrupt will be generated until the user releases the button, depending on how quickly the remote repeats. No IR is processed until that point, which means that holding down a button may not do anything. This also resolves an issue on a Cubieboard 1 where the IR receiver is picking up ambient infrared as IR and spews out endless "rc rc0: IR event FIFO is full!" messages unless you choose to live in the dark.
