Thanks! Yeah, I just did after adding some tracing which dumped out the same data. It looks pretty much the same. Inactive anon and active anon are pretty similar. Inactive file and active file are smaller and fluctuate more, but doesn't look horribly unbalanced. Below are the stats from memory.stat - inactive_anon, active_anon, inactive_file, active_file, plus some commentary on what's happening.
