List probably returns a fairly randomized (per session) list, seeing how it's returning keys() from a QHash. Maybe I misunderstood you on IRC, I thought you'd rather not store a sorted list here. Instead of keeping a sorted cache though, maybe we should just keep the original list in a sorted order?
