> Currently FileCache builds CacheLIRS by using CacheLoader and uses the method {{get(K key}} to retrieve an entry. This can cause the cache segments to be blocked until the entry is loaded into the cache. An alternative is to use the method {{get(K key, Callable<? extends V> valueLoader)}} which would only block the thread loading the same key.
