	  timeout was not properly obeyed.
	  (reported by Peter Bryant <peter@pingability.com>)

6/5/2005

11/24/2003
	- Lookup should check that the name, type, and class in the question
	  section of a response match that of the query.

	  busy client, sockets can be reused fast enough that late responses
	  can come in, and should be ignored.
	  (seen by Joseph Shraibman <jks@iname.com>)

11/17/2003
	- The Lookup code didn't handle CNAMEs pointing at nonexistant names.
