I work in a University setting where we have student's working in our various projects. While some stay with us for a number of years, some are with us for a semester or two. Even with full-time staff, in the almost 6 years I've been here the rest of the dev and design staff completely changed (and grew). In my opinion, if you're not using history/blame your code is relatively new, or you're the only one touching code. Or you have regular code reviews (paired programming, whatever). Seven years at my last job was just full-time staff, but we had the same issues, once a version control system was actually implemented.
