Because the queue is not persistent, it is not crash-safe. In stable versions of MariaDB, we can only try harder to drop all enqueued tables before server shutdown. row_mysql_drop_t::table_id: Replaces table_name. row_drop_tables_for_mysql_in_background(): Do not remove the entry from the list as long as the table exists.
