In Ruby, classes are open. This means that at any time, you can reopen
the class to do stuff to the class, such as adding methods. Any
instance of that class will have that method available, even the ones
created before the change.

In this case, Ryan is adding a class method that internally creates an
instance of the TCPSocket class, and yields it to a block, ensuring
that after calling the block, the socket is closed.

Jesus.
