I don't think so, either. However, I think it was me, not Ivan, who 
added that functionality because I wanted to be able to start the httpd 
with only one pcb.

I don't know about that. I deliberately didn't add this to the 
sequential APIs, since I did not find a standard way to do so on sockets 
(I hadn't considered the netconn API, I must confess). If there is a way 
to do so on any other (BSD-like) socket implementation, I'd strongly 
suggest to follow that instead of inventing our own thing.
