>From dispatch_command() in sql_parse.cc net_end_statement() is called after ha_autocommit_or_rollback() but before close_thread_tables(). What can go wrong in the call to close_thread_tables() after the response to the client? Commit or rollback was done before a response was sent to the client.

/* If commit fails, we should be able to reset the OK status. */
thd->main_da.can_overwrite_status= TRUE;
ha_autocommit_or_rollback(thd, thd->is_error());
thd->main_da.can_overwrite_status= FALSE;

thd->transaction.stmt.reset();

net_end_statement(thd);
query_cache_end_of_result(thd);

thd->proc_info= "closing tables";
/* Free tables */
close_thread_tables(thd);
