The cache generation is used to decide whether user documents obtained during two separate calls are still "fresh". The generation is incremented whenever an "invalidating" event occurs, such as a user update, or a role deletion, etc. However, we're currently incrementing on user acquisition, which doesn't affect persisted state. This is probably harming our cache use, and causing mongos to frequently re-acquire user data.
