gnome dialog run-and-close?

[Jeff Garzik <jgarzik pobox com>]

I remember there was discussion in the recent past about whether or not
to use gnome-dialog-run-and-close.

libgnomeui gurus, what is the Right and Proper(tm) way to display a
simple message box, modal, and then destroy it?  I can do it manually of
course, but I was hoping there was a preferred convenience function
somewhere that I should be using instead.  :)
