title: Eclipse hanging, how to kill it properly?
body: <p>Sometimes my Eclipse hangs and I need to kill it violently. However, I have been unable to do it properly. It seems that kill -9  does not actually shut it down in a proper way since I can still see the hanged window. What command sequence would kill my Eclipse properly so I could restart it?</p>
  
  <p>I am running Ubuntu 12.10 and Eclipse 4.2(Juno).</p>
