I also have holes in almost every project. I am using the latest steam version 1.0.2.2253 Steam RC and default settings for a normal detail model.
I though perhaps this was large triangle removal. The minimum setting is 10. However, when fixing in meshlab and reimporting to RC, the holes reappear on export following any further modifications.
