 Network.Socket.connect checks the !SocketStatus of the socket:
 {{{
 if currentStatus /= NotConnected
 }}}

 From [http://www.opengroup.org/onlinepubs/000095399/functions/connect.html
 The Open Group Base Specifications Issue 6]:
 "If the socket has not already been bound to a local address, connect()
 shall bind it to an address which, unless the socket's address family is
 AF_UNIX, is an unused local address."
