Indeed, there is:

def threaded():
   """ do threaded stuff here """

Thread(target=threaded).start()
Thread(target=threaded).start()
Thread(target=threaded).start()
Thread(target=threaded).start()
Thread(target=threaded).start()


Now threaded() runs five times.

Python is not Java where one has to subclass from Thread (AFAIR the dark
ages where I used to speak Javanese).


Mick,
