I see no unit tests, is that intentional?

looks like we are trying to achieve the consistent state of subscribers in each period of time, and so updates should be performed across the cluster synchronously, to achieve that you can use blocking_updates property, if we won't need that we can manage local concurrent operations using read/write locks instead of LockService.
