You are correct, it does return EINPROGRESS when using a non-loopback
address.

Perhaps I should ask a different question.

Subsequent code to check the socket's status, something like:

	int n;
	socklen_t intsize = sizeof(int);

	getsockopt(f, SOL_SOCKET, SO_ERROR, (void*)&n, &intsize);
	if (n) ...

which works (with suitable cast adjustments) on Solaris, Linux,
Darwin, and yes, even on Windows, doesn't work here.

I have an alternative test that uses getpeername(), but I'm surprised
at the difference in behavior.
