Basicly a database based solution is very simple, it shouldn't have a race condition. I don't think this is a big issue, the default option is a simple one for simple sites, you always need to have a very good understanding of whatever technology you use if you want to go for something bigger. And most well written open source PHP projects that I've seen, have a custom session handler. A highly trafficked site should always override the session handler.
