Perhaps it's a performance thing? As you can always get the peer 
address of a TCP connection, there's no need to return it every time 
you receive data.

I had a quick look through Stevens--he only used recvfrom for 
connectionless examples.

Solaris seems to return a 'from' parameter for all connections, as does 
HPUX. So, I think I agree that it's a strangeness on the part of BSD.
