	As others have pointed out there would not be multiple ports,
	but multiple addresses with a single port number. The
	addresses would then be given out eg. in round-robin
	order. This is how many www-sites balances load between
	multiple machines (my suggestion would distribute the load
	between multiple processes, not machines).

	If my first idea cannot be used (eg. because of limited amount
	of ip-addresses), here is another idea:

	Make the connection server accept eg. 1000 connections (and
	serve them all). After that the server can fork(). The new
	child would then close the main socket that is being listened
	and only serve its 1000 clients. As soon as all the 1000
	clients have closed their connections just exit the child. At
	the same time the parent process closes all the client sockets
	and start again collect a new set of 1000 clients.

	The above method might result in multiple processes, each of them
	handling just few clients. But the system might work fairly
	well, but that is difficult to say without testing.
