    This code works fine but there is a need to explicitly flush data from standard output.
    Haven't found a way where prints would work without flushing.

    import time
    from multiprocessing.process import Process
    import sys
    
    class LongAction:
        def time_consuming_action(self):
            tmax = 600
            for i in range(tmax):
                print i
                time.sleep(1)
                sys.stdout.flush()
            time.sleep(tmax)
            self.tmax = tmax
            return "Slept well"
            sys.stdout.flush()
    
    class LongActionThread(Process):
        def __init__(self, la_object):
            self.la = la_object
            Process.__init__(self)
    
        def run(self):
            self.la.time_consuming_action()
    
    if __name__ == "__main__":
        la = LongAction()
        la_thread = LongActionThread(la)
        la_thread.start()
    
        # After 5 sec i've changed my mind and trying to kill LongActionThread
        time.sleep(5)
        print "Trying to kill LongActionThread"
        la_thread.terminate()
