The lookup cache is a separate caching subsystem that allows arbitrary keys to be associated with arbitrary data. This data is stored in the registry and is persistent. Note that the caches themselves live in locked memory, the registry is used as a backup store and is updated periodically as a background process - so _VCache_Lookup and _VCache_UpdateLookup can be called at event time.
