Someone trying to outperform Oracle's cache

The following code is from a migration project I'm working on. It is part of a package named PERFORMANCE and is run every 15 minutes:

  Declare
  test number;
  Cursor c_worklist
  Is
     select *
     from v_worklist
     where id = v_id;
  Begin

  FOR rec IN c_worklist  LOOP
    test := 0;  -- does nothing
  END LOOP;
  end;

A nice little wtf-snippet. The purpose? According to "the vendor" the cursor that loops through every row in a view is supposed to keep the data in Oracle's cache, and if not in place some web service will time out. I believe we have better tools to keep stuff in cache.
