    Description

      As reported by Edward Capriolo:

      For reference I did this as a test case....
      SELECT * FROM src where
      key=0 OR key=0 OR key=0 OR key=0 OR key=0 OR key=0 OR key=0 OR key=0
      OR key=0 OR key=0 OR key=0 OR
      key=0 OR key=0 OR key=0 OR key=0 OR key=0 OR key=0 OR key=0 OR key=0
      OR key=0 OR key=0 OR key=0 OR
      ...(100 more of these)

      No OOM but I gave up after the test case did not go anywhere for about
      2 minutes.
