This distributed lock implementation has a subtle race condition that can cause two processes to hold the lock simultaneously. Find the bug and fix it. ```python import redis import time import uuid class DistributedLock: def __init__(self, redis_client, lock_name, timeout=10): self.redis = redis_client self.lock_name = f"lock:{lock_name}" self.timeout = timeout self.token = str(uuid.uuid4()) def acquire(self): while True: if self.redis.setnx(self.lock_name, self.token): self.redis.expire(self.lock_name, self.timeout) return True time.sleep(0.1) def release(self): if self.redis.get(self.lock_name) == self.token: self.redis.delete(self.lock_name) ``` Explain why this is dangerous in production and provide a correct implementation.
