You should encapsulate your Tkinter GUI within one thread, dedicated to
just that job, and communicating with all other threads via instances
of Queue.  In my experience (with older releases of Python, Tkinter, and
Tk itself -- haven't tried with the current ones) this is also needed
on Linux -- making calls to Tkinter method from multiple threads can
cause crashes (and I think that is in fact documented).
