title: Chrome doesn't delete session cookies
body: <p>I'm trying to set session cookie in javascript like this:</p>
  
  <pre><code>document.cookie = 'name=alex; path=/'
  </code></pre>
  
  <p>But Chrome doesn't delete it even if I quit browser and launch it again. </p>
  
  <p>I checked in Firefox and Opera and both work as intended - they delete session cookie on browser exit.</p>
  
  <p>Is Chrome just ignoring expiration rules?</p>
  
  <p>I checked in multiple OSes and found out that session cookie gets removed on Chrome in Windows XP and Ubuntu, but NOT in Mac OSX Lion. </p>
