title: Environmental variables are not reloading properly
body: <p>I really don't know how this could happen. So suppose I added the following line to my <code>~/.bashrc</code> file: <code>export asd='asd'</code></p>
  <p>if I now save and reload the terminal: <code>exec bash</code> and I check for the value, it exists:</p>
  <pre><code>$ echo $asd
  asd
  </code></pre>
  <p>All fine and jolly, but when I delete this value, when I remove the line <code>export asd='asd'</code>, and create a new bash instance, the value persists.</p>
  <p>I can modify the value just fine..</p>
