Multiprocessing: Threads work well. Processes don't work.

[viyubu]

Code :

from multiprocessing import Process
import os

def info(title):
    print(title)
    print('module name:', __name__)
    print('parent process:', os.getppid())
    print('process id:', os.getpid())

def f(name):
    info('function f')
    print('hello', name)

if __name__ == '__main__':    
    from time import time
    t0 = time()
    info('main line')
    p = Process(target=f, args=('bob',))
    p.start()
    p.join(1) #####
    print( 'main. end' )
    print( 'Time was :', time() - t0 )

Printout :

main line
module name: __main__
parent process: 4959
process id: 5722

and a dialog box :
