title: Composer killed while updating
body: <p>I got a problem, I tried to install a new package to my Laravel 4 project.
  But when I run <code>php composer.phar update</code> I get this:</p>
  
  <pre><code>Loading composer repositories with package information
  Updating dependencies (including require-dev)
  Killed
  </code></pre>
  
  <p>I have looked for the problem in the Internet and saw that the memory is the problem, I think I don't have enough RAM available, I've checked this I have about 411mb free.
  Does composer really need more RAM?</p>
