Okay, it sounds to me as if you are confusing the thread's existence 
with its state.

Just because a thread has completed its task and is no longer running 
does not mean it does not exist, there is still a C++ object on the heap 
that holds some state, and this object is still referenced by the 
thread_group.

If you want threads to be removes from the thread group once they have 
completed their task you will have to do this yourself, the thread_group 
class doesn't provide this for you.

The way in which you go about keeping track of the threads will really 
depend on what you're doing with them.
