title: Reading the last n lines of a file
body: <p>So like the title of this post says how can i read the last n lines of a file and store them in a List?</p>
  
  <p>Keep it in mind that:</p>
  
  <ul>
  <li>the file is big (somewhere between 5 MB and 10 MB)</li>
  <li>the file may or may not be locked by another thread</li>
  <li>it is accessed by another thread (a new line is added to file when process finished)</li>
  </ul>
  
  <p>Thank you.</p>
