> Internally, INSERT INTO ... VALUES statements use temp table to accomplish 
> its functionality. But temp tables shouldn't be stored in the metastore 
> tables for ACID, because they are by definition only visible inside the 
> session that created them, and we don't allow multiple threads inside a 
> session. If a temp table is used in a query, it should be ignored by lock 
> manager.
