It's a reasonable question. I don't feel strongly about it, but I prefer lock-free programming where practical, and in this case there's really no need for coordination between threads. Indeed, these UUIDs are already designed to avoid collisions between multiple _sessions_ without coordination. So why bother with the lock? Mark
