call thread.interrupt_main()

on *NIX:  os.kill(os.getpid(),signal.XXXX)

or best design your threading correctly with resonable/flexible 
communication channels, e.g. CallQueue:

(infact that latter (example2) uses sys.exit/SystemExit the other way 
correctly: to terminate a thread cleanly in functional style. in the 
same style reverse the mainthread could be terminated cleanly.)
