> The Centralized Cache Management project added a native function for calling {{munlock}}.
 This function is unused though, because Centralized Cache Management calls {{munmap}}, which
implicitly unlocks the memory too.  Let's remove the unused code.  This is a private/unstable
class, so there is no backwards-compatibility concern.
