在python多进程中如何让一个进程休眠而不让其他进程休眠

import multiprocessing
import time

def worker():
    print("Worker process started")
    time.sleep(5)  # 进程休眠5秒
    print("Worker process finished")

if __name__ == '__main__':
    processes = []
    for i in range(5):
        p = multiprocessing.Process(target=worker)
        processes.append(p)
        p.start()

    for p in processes:
        p.join()
