Don't use Gdk.Threads.Enter and Gdk.Threads.Leave, *ever*, unless you
(1) *really* know what you're doing, and (2) *REALLY* know what you're
doing.  GTK+ isn't thread safe -- most toolkits aren't -- and trying to
manipulate widgets from a different thread is tricky, at best.

Instead, use GLib.Timeout.Add (with a small timeout) or
Gtk.ThreadNotify.  You can pass each of these a delegate, which will be
invoked from the GTK+ UI thread, so you don't need to worry about
locking/unlocking the application, cleaning up your code, and
maintaining your sanity.
