ne request and have not yet been released.
     Once all consumers of a resource have released that resource, the resource then goes to cache. If the
     resource is ever returned to a new consumer from cache, it is re-added to the active resources. If the
     resource is evicted from the cache, its resources are recycled and re-used if possible and the resource is
     discarded. There is no strict requirement that consumers release their resources so active resources are
     held weakly.
