JOOI, in "The Lost Worlds of 2001" one of the proposed plot-lines which wasn't used was that HAL tries to kill all the Discovery's crew by opening both inner and outer airlock doors simultaneously.
The hibernating astronauts are killed, but Bowman manages to get to an emergency on-board survival shelter with its own independent oxygen supply.
Having them need to do a spacewalk instead was more dramatic and allowed Kubrick and Clarke to set-up the situation where Frank Poole repeats the spacewalk and is then killed by the Pod.
