twisted简单实现多线程，轮询，后台daemon运行

from twisted.application import service, internet
from twisted.internet import reactor
import time
i=0
def writedata():
    global i
    i+=1
    a=i
    print 'waiting to write data     (%d)'%a
    time.sleep(8)
    print 'writing data!!!!         (%d)'%a
    
def writeinthread():
    reactor.callInThread(writedata)
application =service.Application('timeserver')
tservice = internet.TimerService(4,writeinthread)
tservice.setServiceParent(application )

linux 下
运行命令：twistd -y 脚本名.py
windows下无法放到后台运行。
