[Xen-devel] [PATCH v6 04/13] oxenstored: force FD_CLOEXEC with Unix.set_close_on_exec on LSB init

From: "Luis R. Rodriguez" <mcgrof@xxxxxxxx>

Lets match the systemd active socket activation implementation and
ensure that FD_CLOEXEC is set by usin Unix.set_close_on_exec. David
notes oxenstored likely does not exec but there is no harm in being
careful just in case things change in the future.
