+Subject: [PATCH] Drain the vt file descriptor.
+
+Apparently putting it in raw mode makes the kernel think we really
+really need the events from it, even if we open it write-only, and if we
+don't drain input from it then eventually the kernel starts a wakeup
+storm trying to enqueue keystrokes that'll never go anywhere.  Just eat
+the data and pretend everything's fine.
