I wouldn't bet on even that always being safe.

The way I do it is use a .after event in the main tkinter loop
to check a queue every 20 msec or so. Other threads send commands
through the queue. I usually pass commands as tuples (func, *args, **kw)
so that the .after handler simply calls the func on the args.
