Dialogs in wx are odd beasts. Most objects are gc'd when they go out of
scope, but dialogs are not. I don't know why; I just know that since I started
using wx, the advice has always been to explicitly release dialogs. My
understanding is that wx maintains an internal reference, but I'm not positive
about that.
