Socket file descriptors remain open across exec unless SOCK_CLOEXEC is set. Enable this option, to avoid leaking file descriptors. In practice, this isn't a big deal, since the socket only remains open for a very short period to write a message. However, this socket might leak for for multithreaded programs if an exec occurs between the open and close. Change-Id: Ica2e71fe28657c32d56de1431c8f7f1f5c7b7c58
