Well mine has been sat on idle for ages at times and never overheated.
When filling with coolant it should take 10 minutes max, the car won't have overheated by then.
Airlocks you say, how are you any more likely to get airlocks in a system with a running waterpump, than in a system without one? Water is more dense than air and therefore with some encouragement the air will rise to ths top, whether the engines running or not, which is when you open the bleed point which is at the highest point in the system.
The running would probably help as hot air rises.
