Well, that must be decided on situtation by situation. Most people read a much bigger amount of data than they actually write, and the small amount of data they write is then (almost!) guaranteed to be consistent. For webservers, were only few changes to the static pages are made, this mode is the correct behaviour, for newsservers it's probably not. The way it's done at the moment is ok, IMO.
