from multiprocessing import Pool

def with_app_context(need_new=False):
    def magic(func):
        app_store = {}
        def wrapper(*args, **kwargs):
            print 'inside', args, kwargs
            result = func(*args, **kwargs)
            return result

        return wrapper

    return magic


@with_app_context(need_new=True)
def func(k1, k2):
    print k1, k2
    return 'ret'


pool = Pool(processes=1)
pool.apply_async(func, args=('hi', 'yo'))
pool.close()
pool.join()

什么结果都不输出, 请问哪有bug?
