1. Sync is the biggest problem for IRC, not ordering.
2. As long as the clock is somewhat accurate, then we can prune really old data.
3. Eventually messages will have a cost, so attacking the event graph will be ineffective (trying to make very old branches that nodes will reject).
4. Orphan pool should drop older orphans eventually.
5. We will need good monitoring tools to track the graph.
