They haven't been used yet. Keep throwing data in and it should allocate more pages. The "full" is deceptive... should probably fix that. That just means there's nothing known to be free on the tail... But set'ing a new variable may not cause an eviction or allocate more memory due to finding an expired item on the tail.
