> Whatever happens to have the last shared_ptr to the IoService will run
> ~IoService when the shared_ptr goes out of scope. IoService's destructor is
> responsible for joining all worker threads in the pool. Most callbacks now
> own weak_ptr<IoService> that can be promoted to a shared_ptr in order to post
> new async tasks. If a callback object is the last thing holding the
> IoService shared_ptr it's going to try to join the thread pool inside of one
> of the thread pool's threads.
