This fixes a plethora of "not indexed" errors when the document has not been indexed. * Message handler throws NotIndexed if not overdue * The message is put into backlog and tagged with backlog_path * path2backlog[path] tracks backlog associated with document `path` * The backlog is cleared when the index is merged * backlog[0] is forced to run if it becomes overdue
