 The problem is that getanswer() only adds ai_canonname to the first 
 element of the list.
 reorder() is then called and depending apon the order of the records 
 returned from
 the DNS the addrinfo structure without the ai_canonname set is moved to the
 start of the list.
 
 The solution is to have getanswer() set ai_canonname on ALL elements in 
 the list.
