Since the option can be set/reset for each socket, the default setting 
should be the one which satisfies most naive socket uses, and IMHO this 
would be the batch file transfer kind of stuff. TCP_NODELAY only makes 
sense for realtime applications where interactive response is critical, 
such as Croquet, and these applications should know what they're doing 
and should set TCP_NODELAY...
