Should we maybe be using util_memoize for the caching so that clustering (multiple web servers) is properly handled?
Looking into util_memoize, I wonder where it deals with server clusters - I just see calls to ns_cache. Did this functionality disappear or am I looking in the wrong place?
Til, iirc it only sync's flushes (look for ncf.send in the code).
