bug描述 Describe the Bug

多线程使用jieba+paddle时，会报各类错误/段错误，MemoryError是其中一种
多进程即multiprocessing下运行是OK的，稳定不报错。

MemoryError: (ResourceExhausted) Another thread is waitting. (at /paddle/paddle/fluid/framework/new_executor/workqueue/events_waiter.cc:104)

import _thread as thread
import jieba
import jieba.posseg as pseg
import paddle
paddle.enable_static()
jieba.enable_paddle()

def call_pseg():
    while True:
        text = "你好"
        s = pseg.lcut(text, use_paddle=True)

def main():
    t_num = 6
    for i in range(t_num):
        thread.start_new_thread(call_pseg, ())
    while True:
        pass

main()

系统为Ubuntu 20.04（docker镜像，cpu下运行）
python版本为3.8.10

你好，经过分析，初步判断是新执行器问题，目前尚未定位到具体原因，可先通过设置FLAGS_USE_STANDALONE_EXECUTOR=0使用旧执行器来避免该问题，修复该问题后，我们会尽快回复您。
