title: pip install - killed
body: <p>I'm trying to install package with pip on Ubuntu server:</p>
  
  <pre><code>$ pip install MySQLdb
  Downloading/unpacking MySQLdb
  Killed
  </code></pre>
  
  <p>And it's getting killed. There is enough free RAM on server. Why it is killed?</p>
  
  <p>UPD
  Logs:</p>
  
  <blockquote>
    <p>Out of memory: Kill process 6627 (pip) score 297 or sacrifice child</p>
  </blockquote>
  
  <p>Thats strange, because I have about 150 mb free RAM.</p>
