Yes, all copies of undelivered handlers are destroyed when the
io_service destructor is called. You just need to make sure that
any resources that may be associated with the handlers are
destroyed. Using shared_ptr/enable_shared_from_this as the
tutorials do will take care of this.

Oops, yes that used to be the case, but it's no longer right. I
should remove that comment. Thanks for pointing that out.
