Therefore, I would think that leaving it running for up to a minute or two makes sense.
My TD's lowest idle usage is 0.52-0.54 liters per hour after warming up and without extra loads. With lights, radio, ventilation, and/or A/C that can easily get to 0.80-1.20 lph. I've checked in 2-3 gassers with similarly sized engines that they have the same fuel consumption at idle, so it's about even. If one is worth shutting off, then so is the other.
