Your example is somewhat complicated to say the least. As I am not using
2.3/8.4 at the moment I have not encountered like problems. But note that
there are fundamental differences between Tk.quit and Tk.destroy. Tk.quit
just leaves the event loop and touches no widget. See this example:

  from Tkinter import *
  m=Tk()
  Button(m,text="quit",command=m.quit).pack()
  mainloop()
  print "this is not The End"
  mainloop()

Maybe destroy did not trigger Python garbage collection in 8.3 as expected,
so data could have been erronously accessable. The memory leak would not
have been to obvious because destroy is a rare instruction...

May also be there is some bug with destroy in Tk 8,4 ;-)
