Description
When duplicating a tcpip socket (file descriptor if you like) the no-inherit and close-on-exec flags aren't cleared as they should. This results in code doing socketpair(); ... dup2(fds[1], 1/*stdout*/); _spawn(); to fail. (On example of this is the cups code.)

(In [3382]) clear the no-inherit and close-on-exec flags when duplicating a tcpip socket. Fixes #172.
