Whether 'was_deleted' was 'TRUE' or not, eventually we have to remove self from '_acquired_locks'. For example: 1. App #1 with coordinator 'A' wants to release lock "b" 2. 'self.coord.client.delete()' failed for some reason(.e.g, BrokenPipeError,MemcacheUnexpectedCloseError) 3. According to the former logic,lock "b" will not remove from "_acquired_locks", so "self.heartbeat()" will make it alive forever until App #1 was down or lock "b" turned expired. 4. Now App #1 with coordinator 'A' wants to acquire lock "c", who have the same lock-name with lock "b",It is clear that this will fail and prevent the locked program from continuing to execute.
