I just use the unix socket code from the SVN tree since os-x drawin  
is unix after all.

I have some changes related to EINTR (attached) for the old socket  
code, but have not anyone tested it.

So for example  socketReadable()
invokes recv() to see if the socket is readable.
If that got a EINTR the original code would return (-1)  EOF
This likely is the wrong answer since you might expect back  (1)  
meaning data, or (0) meaning would block.

Thus something like sqSocketReceiveDataAvailable() does this below so  
it *could* get a EINTR which would set the socket to
OtherEndClosed, which in fact is wrong.

   if (SOCKETSTATE(s) == Connected)
     {
       int fd= SOCKET(s);
       int n=  socketReadable(fd);
       if (n > 0)
	{
	  FPRINTF((stderr, "receiveDataAvailable(%d) -> true\n", fd));
	  return true;
	}
       else if (n < 0)
	{
	  FPRINTF((stderr, "receiveDataAvailable(%d): other end closed\n",  
fd));
	  SOCKETSTATE(s)= OtherEndClosed;
	}
