Disabling do_sort() does not work.

Hi,
I would like to replace MonetDB' sorting algorithms (timsort/quicksort) with my own.
As the first step, I commented all content of function *do_sort()* in gdk_batop.c to disable the sorting functionality.
Then I re-build the monetdb (with no error) and type a SQL statement with ORDER-BY clause in mclient interface:
"select o_orderkey, o_custkey, o_orderstatus from orders order by o_custkey limit 10;"
I was expecting to see the dis-ordered result. However, it turns out that the result is still ordered by o_custkey.
I am confused about the result. Did I miss something? Any help would be great.
Best regards, John
