Its because people tend to tune their models to suit their machines, rather than tuning their machines to make accurate renditions of their models.

The problem is we're not quite there yet, but some people seem to think that, and complain a lot about it.

The main reason holes come out way too small is due to segment pausing, which I have never suffered from because I use 100Mb Ethernet instead of serial over USB..

Even if the machine is perfectly calibrated, holes will still come out too small.

I have the M8 hole diameter small so I can drill it out. As I have a Bowden cable, I always end up with a blob on each layer as it stops and retracts (perhaps I should change the path order from Loops > Perimeter > Infill to Perimeter > Loops > infill?), so have to drill it out anyway. I don't seem to have observable segment pauses, but looking at the stls and the path Skeinforge produces, I would say there are 13 facets on a 8mm and 6 facets on a 3mm hole.
