qtconsole and cx_freeze

[neurochen]

Describe the bug Hi, thanks for the wonderful qtconsole! We are embedding a python console in our pyqt app, using qtconsole. However, when we ran the exe from cx_freeze, it constantly reopened more and more qtconsole window. And the old console always displayed "Kernel died, restarting." Could you please take a look at it?

To Reproduce Install cx_freeze first and then cx_freeze the script below.

if __name__ == '__main__':
    import multiprocessing
    multiprocessing.freeze_support()
    from qtconsole.qtconsoleapp import main
    main()
