        From what I read in the demo sources, the reverser server is
listeing on INADDR_ANY; getLocal should return that value, could you
confirm it?

        When StopServer builds the TCPStream object, it tries to
connect to INADDR_ANY and this seems to be what fails on Win32. I am
not familiar with this problem, but the winsock reference says the
following about WSAEFAULT:

        "The name or the namelen parameter is not a valid part of the
user address space, the namelen parameter is too small, or the name
parameter contains incorrect address format for the associated address
family."

        I suppose that the win32 connect does not like INADDR_ANY and
crashes. 

        We could add a check in Socket::getLocal so that when in win32
and the address is null, 127.0.0.1 is returned, but I think we should
not, since we would lose the possibility to know that an InetAddress
object has the INADDR_ANY value.
