Indeed. The confusing thing is that IDisposable IS implemented on GTK#
widgets but doesn't call Destroy -- and sadly, this can't be changed
without breaking backwards compatibility.

However, this needn't be the case for new widgets. The first thing I
do when subclassing Dialog is to override Dispose with a version that
calls Destroy. Then I can use the 'using' pattern:
using (MyDialog dialog = new MyDialog ()) {
    somevalue = dialog.Run ();
