Yes, but the point is that applications shouldn't have to worry about
the fact that GTK-VNC uses threads internally - we explicitly used
coroutines so apps wouldn't have this complication. They should be able
to use any GTK calls they like with GTK-VNC. So we have todo a better
job of hiding the fact that we use threads by emitting signals from the
main thread.
