Many main loop implementations allow you to embed a different main
loop within them. In your "main" thread, see if you can call
gtk_main_context_iteration() regularly with may_block = FALSE instead
of running the glib main loop full time in its own thread. This should
eliminate the need for inter-thread communication.
