-----------------------------------------

Yeah might be a good idea, so that it is actually a repeatable test

> exchgpartition2lel test fails if all tables are changed to MM, because of write ID mismatch between directories and tables when exchanging partition directories between tables. ACID should probably fix this because transaction IDs are global.
> We should add a test after integrating with ACID; if it doesn't work for some other reason, we can either implement it as moving to a new mm_id/txn_id in each affected partition, or block it on MM tables.
