+a few fixes for getfd suggested by Lennart
+
+I am currently investigating how to best integrate PulseAudio with
+ConsoleKit/PolicyKit. While doing that I had a look on your code, and
+found a few issues in getfd.c I'd like to report, before I forget
+them. I couldn't find any bugzilla with at consolekit project (neither
+fedora, nor fdo, nor gnome?) hence I am mailing you in person.
+
+In getfd.c in open_a_console() a close() is missing if is_a_console is
+missing.
+
+The open() in open_a_console() should probably use O_NOCTTY. Otherwise
+C-c on the console might end up in a SIGINT to your daemon process!
+
+Also I'd add an isatty() check to is_a_console(), to makes sure that
+you're actually talking to a TTY before you issue KDGKBTYPE on
+it. ioctl()s are unfortunately not unique, hence i'd recommend that check.
+
+That's it,
+
+Lennart
