+///
/// ## EXTREMELY IMPORTANT
-///
+///
/// It is extremely important that your [`KVStore::read`] implementation uses the
/// [`io::ErrorKind::NotFound`] variant correctly: that is, when a file is not found, and _only_ in
/// that circumstance (not when there is really a permissions error, for example). This is because
///
/// # Pruning stale channel updates
///
-/// Stale updates are pruned when a full monitor is written. The old monitor is first read, and if
-/// that succeeds, updates in the range between the old and new monitors are deleted. The `lazy`
-/// flag is used on the [`KVStore::remove`] method, so there are no guarantees that the deletions
+/// Stale updates are pruned when the consolidation threshold is reached according to `maximum_pending_updates`.
+/// Monitor updates in the range between the latest `update_id` and `update_id - maximum_pending_updates`
+/// are deleted.
+/// The `lazy` flag is used on the [`KVStore::remove`] method, so there are no guarantees that the deletions
/// will complete. However, stale updates are not a problem for data integrity, since updates are
/// only read that are higher than the stored [`ChannelMonitor`]'s `update_id`.
///
/// consolidation will frequently occur with fewer updates than what you set here; this number
/// is merely the maximum that may be stored. When setting this value, consider that for higher
/// values of `maximum_pending_updates`:
-///
+///
/// - [`MonitorUpdatingPersister`] will tend to write more [`ChannelMonitorUpdate`]s than
/// [`ChannelMonitor`]s, approaching one [`ChannelMonitor`] write for every
/// `maximum_pending_updates` [`ChannelMonitorUpdate`]s.
