> At SU we have a case where we'd like to be able to, by default, sync every appended edit
but for some tables have the control to disable their sync. You could then rely on other tables
like .META. to do syncs, the optional log syncer timer down in LogSyncer and user tables that
are always synced. For example, set a 10ms timer on the log syncer so that in the worse case
you lose 10ms of non-catalog edits.
