Ed's writeup is great. Here's another that goes into several reasons holes are undersized, and a workaround: http://hydraraptor.blogspot.com/2011/02/polyholes.html

You can use low vertex count polygons instead of holes to improve their sizing.

Thanks! that useful info to learn (and in general an interesting blog).
