示例1: test_terminate

# 需要导入模块: from multiprocessing import pool [as 别名]
# 或者: from multiprocessing.pool import map_async [as 别名]
def test_terminate(self):
        if self.TYPE == 'manager':
            # On Unix a forked process increfs each shared object to
            # which its parent process held a reference.  If the
            # forked process gets terminated then there is likely to
            # be a reference leak.  So to prevent
            # _TestZZZNumberOfObjects from failing we skip this test
            # when using a manager.
            return

        result = self.pool.map_async(
            time.sleep, [0.1 for i in range(10000)], chunksize=1
            )
