The hack causes deadlocks and other interesting problems and it really can only be fixed properly inside GLib. We will include a patch for GLib in our builds for now that handles this, and hopefully at some point GLib will also merge a proper solution. A proper solution would first require to refactor the polling in GMainContext to only provide a single fd, e.g. via epoll/kqueue or a thread like the one added by our patch. Then this single fd could be retrieved from the GMainContext and directly integrated into a NSRunLoop. https://bugzilla.gnome.org/show_bug.cgi?id=741450 https://bugzilla.gnome.org/show_bug.cgi?id=704374
