rerun flake stateful test failure and comment to #7856

A test:

Case1: if the compact deal with block, we can abort: -- can be aborted

mysql> optimize table t7861 compact;
^C^C -- query aborted
^C^C -- query aborted
^C^C -- query aborted
^C^C -- query aborted
^C^C -- query aborted
^C^C -- query aborted
ERROR 1152 (08S01): Code: 1043, displayText = Aborted query, because the server is shutting down or the query was killed.

Case2: drop table xx all; -- can not be aborted
It seems we can't deal with block, so this case can not abort.
