Well, i am not sure how you are using gtk, etc, but here is the basic
You can't touch gtk+ from threads other than the main thread. What
thread notify does is a small trick to get the function you setup to
thread notify running in the main thread. That way you can do gui
interaction from that code. There are other ways to managed this, and
how do you so is up to you. But making sure you are in the main thread
before touching gtk objects is a good thing.
