wxMessageBox with an auto-close timer in wxPython

Platform and Python installation info:

Platforms: Windows, OS X
Python: Active State Python 2.7
wxPython: Version 2.9

Here is a sample code in which I use a wxMessageBox:

import wx,os

class Frame(wx.Frame):
    def __init__(self, parent, id, title):
        wx.Frame.__init__(self, parent, id, title, size=(100, 100),style=wx.MINIMIZE_BOX | wx.SYSTEM_MENU | wx.CAPTION | wx.CLOSE_BOX | wx.CLIP_CHILDREN)
        
        host=os.system('hostname')
        if host!='superman':            
            self.dialogBox=wx.MessageBox('The host name should be superman. Closing this dialog box in 2s...','Info')            
            self.Destroy()
        else:
            self.Center()
            self.Show()
            
if __name__ == '__main__':
    app = wx.App(redirect=False)
    frame = Frame(None, -1, 'Sample')
    app.MainLoop()

Select allOpen in new window

According to the above piece of code, If the host name is not 'superman' , then the user is displayed a message box and prompted to press 'OK'. If the user presses 'OK' button on the message box, then the control moves to the next line in the code (i.e., line number 10) where the frame is destroyed. I want to be to able to automatically close the dialog box and go to the next line in the code i.e., self.Destroy() if the user does not press the 'OK' button in the next 2 seconds. Any thoughts on how do I do that in wxpython ?
