Paddle1.6与Multiprocessing冲突

运行环境： cuda9.0 cudnn7.3 linux
测试代码：

import paddle as p
import paddle.fluid as f

import multiprocessing as mp


def func(a):
    print('helloworld')
    return a + 1

print(p.__version__)
pool = mp.Pool(3)
pool.map(func, [1,2,3])
pool.terminate()

使用PaddlePaddle1.5运行输出：

1.5.2
helloworld
helloworld
helloworld

使用PaddlePaddle1.6运行输出：

1.6.0
helloworld
helloworld
helloworld

请问后面这堆log是什么原因导致的，是不是发生了内存泄露？
