Won't work. If it did, it'd just bring us back to the
pathetic situation we had in 2.3.51, but with the
introduction of inactive_clean pages and an inactive
target all this test would do is either preventing
us from ever making the inactive target or from getting
the eviction balancing between zones right (see 2.3.51).
