The usecase is pretty simple:  you have a loadbalancer and remove  one 
backend Zope. The LB detects the removal and stops forwarding request.
When the client comes back (means Zope opens the ports early) the LB
will start forwarding to the client although it might take a while until 
the Zope instance is really up and ready to serve request. So by opening
the ports late we are able to reduce the latency and avoid pending
requests.
