I found this mail from Paul Pogonyshev very helpful:

http://mail.gnome.org/archives/gtk-app-devel-list/2004-July/msg00176.html

It shows how to get a background thread to post data to the GUI thread
over an GAsyncQueue, and have the GUI thread woken up automatically
(no timeout polling). I was using a pipe for this and having awful
problems on win32. With Paul's code I have a slick cross-platform
threaded app, very nice.
