Description

git.commit.id.abbrev=e92db23

I tried running the below sequence of commands from sqlline :

select count(*) from widestrings;
+------------+
|   EXPR$0   |
+------------+
| 10001      |
+------------+

select * from widestrings;

Cancel the running query while it is printing the output

select count(*) from widestrings;
This causes SQLLINE to hang indefinitely.

We should see this problem when we kill a query in sqlline while it is displaying the output. If needed I can provide the data that I used.
