如果回收了在有效期内的key对应的value空间，在释放原有空间前会休眠一小段时间。
对应的配置项如下：
# sleep time to avoid other processes read dirty data when
# recycle more than one valid (in TTL / not expired) KV entries
# 0 for never sleep
# unit: microsecond (us)
# default: 0
value_policy.sleep_us_when_recycle_valid_entries = 1000

嗯，明白了，如果对于数据正确性比较敏感的场景，在读操作上还是加锁比较好的。
