Tcl/Tk is compiled threaded. Tkinter is supposed to work with the
threaded Tcl/Tk, although not all applications using Tkinter assume a
threaded Tcl/Tk.

"If you have created a toplevel in a Tk thread, it should only be
accessed by the thread in which it was created.  This is 
because Tcl uses apartment model threading (like Perl).  A 
toplevel or widget that is created in one Tk thread only exists 
in that thread."
