Adam Holmberg commented on CASSANDRA-16160:
-------------------------------------------

Confirmed that it's the result of paging. Looking back a bit, I don't think 
this behavior has ever been different. [~dcapwell] I'm wondering if 
{{3.0-rows.results}} was just selected with page size set higher.

Anyway, here is a potential patch and test.
