console-kit-daemon Hogging CPU and RAM

1. Kill the console-kit-daemon process if it's still running.
2. Remove the file
   /usr/share/dbus-1/system-service/org.freedesktop.ConsoleKit.service
   (or move it to some place where you could restore it, if necessary).
3. Reboot and you will see that console-kit-daemon no longer automatically starts up.

I disabled it by removing the executable's exec permission:

chmod -x /usr/sbin/console-kit-daemon
