如何避免apscheduler将任务添加到子进程？

Question

我在我的程序中添加了一个apscheduler的任务，然后我发现我的子进程也有这个任务，结果我的主进程和子进程同时执行这个任务...

主程序是

server = StreamServer((server_ip, server_port), serve_forever, spawn = pool, backlog=100000)

for i in range(process_count - 1):
    Process(target=serve_forever, args=()).start()

我的apscheduler设置是

   scheduler =BackgroundScheduler()
    scheduler.add_job(tick, 'interval', seconds=3)
    scheduler.start()

输出结果是

Tick! The time is: 1409042763.26 pocess is 11428
Tick! The time is: 1409042763.26 pocess is 11431
Tick! The time is: 1409042763.26 pocess is 11424
Tick! The time is: 1409042763.26 pocess is 11430
Tick! The time is: 1409042763.26 pocess is 11426
Tick! The time is: 1409042763.26 pocess is 11380
Tick! The time is: 1409042763.26 pocess is 11425
Tick! The time is: 1409042763.26 pocess is 11429
Tick! The time is: 1409042763.26 pocess is 11432
Tick! The time is: 1409042763.26 pocess is 11433

一些建议：

1. 在创建了子进程之后再启动调度器。
2. 在子进程中关闭调度器。
3. 用其他方法创建子进程，而不是直接从主进程分叉。
