Isn't the standard solution to use a queue for updating the GUI?
At least I didn't have any problems at all with my one TKinter app, I
think the method is described in the Python Cookbook.
The 2nd edition, Recipe 11.9 Combining GUIs and Asynchronous I/O with
Threads gives an example that processes items in the queue 5 times a
second.
I can understand the desire to avoid the put and get overhead and the
poll wait by calling a gui method directly. This works when one uses
tcl/tk compiled with thread support and avoids inter-thread deadlocks.
See my answer to Chris A. for details.
