That seems a bit complex. Why not just register the file
descriptor and read-handler with Tk?
That way the read-handler gets called by Tk's event loop
anytime there's receive data waiting. No extra thread, no
If the read-handler takes a _long_ time to complete, it does
make your GUI pause, so that may be a concern.
Unless tk.createfilehandler isn't supported no Wni32
