 Description   

With our tpch1 data run this in the MariaDB client:

select l_orderkey, l_quantity, l_shipinstruct from lineitem group by l_orderkey, l_quantity, l_shipinstruct;

Immediately hit Ctrl-C a few times until the client exits. It may take a couple of tries to trigger it.

For QA: see description, should crash ExeMgr roughly 1/4 times.
