Yes, if you know about the key. But size(), keyset() and so on are not
aware that this particular key is not loaded.
So you'll never know if you have all entries in cache... so you need to
dig into the cache loader by yourself :-/
This is a bit unsatisfying, rhauch wrote also ISPN ticket for this
problem :-)
This problem appears, when you start seeing ISPN not only as cache in
classic way, but as storage.
I think the problem is in the keySet() and entrySet() methods. These were originally
included as a part of extending ConcurrentMap, but IMO these methods are not practical for
a data store.
