This issue is uncovered by the DMLRate test in Autopilot.

set autocommit=0;
select unix_timestamp();
insert into lineitem values(700000000,10000,1000,1,10,950.50,0.03,0.02,'N','O','1999-01-01','1999-01-01','1999-01-01','DELIVER IN PERSON','TRUCK','test test test test test');
select unix_timestamp();
commit;

The commit command does not commit the transaction. Another query session did not see the inserted row and the table lock remained in place.

If the "select unix_timestamp();" after insert is omitted, then the transaction worked as expected.
