Is it really true that you _have_ to have one thread touching the
gtkmm-functions? At least with gtk+ you can update the gui from multiple
threads if you use gdk_threads_enter()/leave(), I have done so successfully
in a few projects. However, it might be easier to do all gui-related work in
the main thread, but I really wonder if it really is a requirement?
