I agree, the doc needs to be more precise on these corner cases.

Good timing as I have this exact same question.
The problem is there is no "thread finalize callback" to use as that would be ideal. It seems the only way that you can know that a thread is done is by using g_thread_join, which causes the current thread to wait. So, for now, what I did was spin up a thread to handle the thread that I care about so I can wait for the other thread to finish using the g_thread_join method. Then I use a signal to tell me when that thread is finished (ie, gets passed the g_thread_join call).

It would be nice to know what the official line on this is...the docs state "There are better ways to find out if your thread is still alive" but does not offer up what that better way is. It seems that a callback would be the most flexible way to handle it.
