I haven't gone through the exercise, but what does accept(2) do when 
close(2) is called on the socket from another thread?

Intuition tells me that something will happen on the thread that called 
accept().  Perhaps accept returns -1.  If this is the case you could 
check to see if the socket was closed and throw the exception.
