Maybe it wasn't clear, I'm asking about how to do this with WEBrick.

I don't create the socket, WEBrick does. I can't find a WEBrick API that
gives me back the socket, so I don't have a way to call
#getsockname on it to find the port.

I also can't find a WEBrick API where I create the TCPSocket and pass it
in, that would work for me, too.

So that's my question... how do I access the underlying socket so I
can call #getsockname and find what port its listening on?

Thanks,
Sam
