    Causes python to exit without garbage-collecting any objects, and thus
    avoids calling object destructor methods. This is a sledgehammer
    workaround for a variety of bugs in PyQt and Pyside that cause crashes
    on exit.

    This function does the following in an attempt to 'safely' terminate
    the process:

    * Invoke atexit callbacks
    * Close all open file handles
    * os._exit()

    Note: there is some potential for causing damage with this function if you
    are using objects that _require_ their destructors to be called (for
    example, to properly terminate log files, disconnect from devices, etc).
    Situations like this are probably quite rare, but use at your own risk.
