PROBLEM When truncating single tablespace tables, we need to scan the entire buffer pool to remove the pages of the table from the buffer pool. During this scan and removal dict_sys->mutex is being held ,causing stalls in other DDL operations. FIX Release the dict_sys->mutex during the scan and reacquire it after the scan. Make sure that purge thread doesn't purge the records of the table being truncated and background stats collection thread skips the updation of stats for the table being truncated.
