Network.Socket.connect checks the SocketStatus of the socket:
if currentStatus /= NotConnected
From 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."
