Backport patch to work around a server bug.  Server incorrectly handles the
following:  select 1; commit; set autocommit true;
If this is submitted in one call to the server (the select 1 doesn't start a
new transaction like it should), however if the select 1 is sent as a separate
call then it works correctly.
