when I was a kid we were told not to let our dirt bikes idle too long, that they needed a blip now and then to make sure enough oil was present to keep the piston lubed. I think I still have this mindset with a saw. No piss revving, just a blip here and there between cuts. Just habit, not really necessary.
It also gets the chain oiled between long cuts.
