How about EACCESS? EACCESS is within the POSIX spec for connect(), but it 
currently has no documented use for TCP connections. That way we don't need to 
invent a non-standard error number so the userland code is more portable and 
the patch may end up being mostly documentation to explain how the use of 
EACCESS has been extended.
