+60 processes of console-kit-daemon, why?

I have over 60 processes of console-kit-daemon that just won't stop reappearing after I've used sudo killall console-kit-daemon and I have no idea what the daemon is for.

Some clearity, please? I'm running ubuntu 10.04

• They're not processes, they're threads under one process.

  By default htop shows threads and in this case, is very misleading. You can alter this by going into Setup (F2), Display options and checking Hide userland threads. Press F10 when you're done.

  Zolomon : Oh, thanks a whole bunch!
