There is performance issue when closing an object. The slow down is due to the search of the "tag_list" to find out the "corked" status of an object. The fix: (1) Add a counter "num_objs_corked" in the cache structure to track the number of "corked" objects. (2) Skip the search of "tag_list" if the counter is zero i.e. no "corked" objects.
