I don't know much about SCs memory, I am sticking to the .chk itself for now
But I, too would be surprised. I can't see any benefits one could gain from that, just a longer loading time...
Well, if the neutral units are placed first - minerals and gas especially -, there won't be so many holes in the unit list during the game (melee), because minerals usually don't get killed so fast.But eventaully they, too will disappear. And even this does not sound like it would bring any advantages with it...
