- This updates the spend pruner to use a single notification channel to keep the order and processing of connectiong and disconnections deterministic. - The process lock is now held when spend journal entries being removed by the pruner to ensure. - The spend pruners lifecycle process uses an unbuffered channel to recieve and process notifications. Notifications are sent via goroutines to avoid blocking as a result. - Comment related wrapping issues have been resolved.
