Sadly, this is what I recommend as well, especially if you ever want to run on win32. I would caution against overuse of g_idle_add though. Recently I've been saving off the data from the thread and then doing the GUI updates at the start of the next expose/draw. That's worked a lot better for me than idle callbacks, but that's just my own experiences, it might not work so well if you're trying to show a dialog box.
