Igor Canadi b13bdfa500 Add a call DisownData() to Cache, which should speed up shutdown ... Summary: On a shutdown, freeing memory takes a long time. If we're shutting down, we don't really care about memory leaks. I added a call to Cache that will avoid freeing all objects in cache. Test Plan: I created a script to test the speedup and demonstrate how to use the call: https://phabricator.fb.com/P3864368 Clean shutdown took 7.2 seconds, while fast and dirty one took 6.3 seconds. Unfortunately, the speedup is not that big, but should be bigger with bigger block_cache. I have set up the capacity to 80GB, but the script filled up only ~7GB.
