LRU Eviction + fast eviction processing does not work for large %% of IMMORTAL objects #16

When we have 50% of cache population IMMORTAL (pinned) object default eviction processing OffHeapCache.processEvictionFast in LRU does not work 100%. It seems that 25% of IMMORTAL is OK. Consider switching to more complex eviction processing.
