这个python代码创建了多个process子进程，创建完成后先start()，最后统一join，这样所有子进程会并行执行。
from multiprocessing import Process
import sys, os
import time
def timetask(times):
time.sleep(times)
print time.localtime()
def works(func, arg, worknum):
proc_record = []
for i in range(worknum):
p = Process(target = func, args = (arg,))
p.start()
proc_record.append(p)
for p in proc_record:
p.join()
if __name__ == '__main__':
arg = 5
procs = 4
works(timetask, arg, procs)
