from your readme:

> GTK# and other gtk bindings supply a method to callback to the main
thread, which gtkmm does not.

I'm pretty sure it does. Or rather, GLib does, and GTK uses the GLib main
loop, and glibmm/gtkmm wrap both of those.

You simply connect to Glib::signal_idle(), passing a callback, which will
be called once the GLib main loop is running and has nothing of a higher
priority to do.
