How to interrupt a process correctly in windows so catch and finally get executed.

    # DON'T USE THIS!!! THIS WON'T WORK AND GENERATES A COMPLETELY DIFFERENT
    # SIGNAL NOT RECOGNIZED FROM PYTHON AS KEYBOARDINTERRUPT!!!
    #os.kill(pid, signal.CTRL_C_EVENT)

        # its process since it corrupts the queue and blocks permanently (even
        # with a specified timeout).
