The handler slot of a threaded server instance should be set to a quotation which handles client connections. Client handlers are run in their own thread, with the following variables rebound:

•	input-stream
•	output-stream
•	local-address
•	remote-address
•	threaded-server

An alternate way to implement client handlers is to subclass threaded-server, and define a method on handle-client*.

The two methods are equivalent, representing a functional versus an object-oriented approach to the problem.
