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.
