> There's an entire thread (that loops through every stat in the system) for this one single stat (from Cache.cc):
> IOCORE_RegisterStatUpdateFunc("proxy.process.cache.bytes_used");
> I believe we can eliminate this entirely, and use the "cb" field instead, i.e. change the define for the above macro to use RecRegisterRawStatUpdateFunc() instead. This feature, "UpdateFunc", is only used by this one single stat, and I'm fairly sure it's a legacy / remnant that should have been eliminated. Doing this, will allow us to eliminate this thread completely.
