The Racker Hacker IMHOis confused on the fact that writing a 3 to drop_caches and then syncing will destroy the cache. If I read vm.txt well, it states that the action is just going to free less cache. But I must first experiment to confirm that I'm right, and he's not.

The OOM killer may be called even when there is still plenty of memory available
