(trunk gtk) gah, I'm so stupid. I go to the trouble of writing a backwards-compatable wrapper for gdk_threads_add_timeout_seconds(), but then when rewriting the "create torrent" ui and I need to use a timer to update the progressbar, what do I use... my fingers have "g_timeout_add" programmed into them.
