I guess a good question would be "does ruby's TCPSocket take advantage 
of a TCP half close and still received data after it sends a FIN 
advising the other side that it will not be sending any more data?"  I 
have consulted the "TCP/IP Illustrated", but it is apparently a decision 
that is up to the application developer that does the implementation. 
Perhaps my understanding is skewed and this is even a deeper question. 
Does Ruby's Net::TCPSocket class use the underlying OS's TCP/IP stack? 
I think that it would, but I am not yet skilled in the Ruby Way, or it's 
underlying code.  I am still consulting RFC 2822 so my next post should 
include more educated questions.
