I suppose it depends on the definition of the lifetime of the thread. 

A check of the FreeBSD code (thr_join.c) shows it searches for dead threads in
the join call and the search passes without error (thr_list.c). I cannot see
where the thread is removed from the thread hash table and so what defines the
lifetime of a thread. The join call does clean up via the exit path
(thr_exit.c).

I think we need to understand better what is expected and how we are suppose to
handle this.
