I don't know, but wxWindows might not be thread-safe.  I don't yet
know of a GUI toolkit that is.  (GTK+, Swing, and Tkinter aren't)  My
suggestion is to create a thread that is dedicated to interfacing with
the GUI.  All other threads should then send callable objects to that
thread and request that they are executed a la
javax.swing.SwingUtilities.invokeLater()  in Swing.
