commit 4c70a5b405d2ee6b8a47118fd731a0fb64dda2ff
Author: Andrew Bartlett <abartlet at samba.org>

socket_wrapper Cope with SOCK_CLOEXEC and SOCK_NONBLOCK flags
Heimdal will, on supporting systems, set these flags in the type
argument of socket(), causing breakage when combined with
socket_wrapper.
For background on these flags, see http://lwn.net/Articles/281965/
