+Subject: [PATCH] Lock input but don't lock screen
+
+This patch keeps the screen unlocked but keeps the input locked.
+That is, the screen is not affected by slock, but users will not
+be able to interact with the X session unless they enter the correct password.
+
+There's a lot of extraneous code that can be removed since the goal is
+for input to be locked while at the same time allowing the screen to be
+updated and viewable. But this patch just works (tm) and I don't want to
+potentially introduce bugs.
