+xss-lock
+========
+
+Description
+-----------
+xss-lock(1), when used with the `-l` option, coordinates locker activation with
+the login manager using a delay lock (via a file descriptor). Any locker
+application being used with xss-lock can communicate that locking is complete
+by closing the file descriptor set in the `$XSS_SLEEP_LOCK_FD` environment
+variable. This makes sure that suspend waits till the locker has started up.
+Otherwise, the screen's contents may show up briefly for a short time after
+waking up.
+
+This patch adds the ability in slock to detect if `$XSS_SLEEP_LOCK_FD` is set,
+and if so, close the file descriptor once locking is complete.
