But IIUC, INTERNAL cache state is meant only for the cache in the 
current directory.  There is a notation in the LOAD_CACHE documentation: 
"INCLUDE_INTERNALS can be used to provide a list of internal entries to 
be included. Normally, no internal entries are brought in. Use of this 
form of the command is strongly discouraged, but it is provided for 
backward compatibility."
