When do you expire your sessions? If I recall correctly, Django defaults to a two week expiry after the last session change. Remember that Disqus is a rather large network. We have many millions of "active" sessions by the definition above. The load of requests/second and number of sessions in VM really brought out the issues we ran into. I imagine it'd work just fine for sessions for most sites - but I still lean toward projects that specifically aim to be disk-backed k/v stores (membase, etc).
