title: Php max_execution_time ignored
body: <p>Hi i'm trying to stop long running php scripts</p>
  
  <p>so i've created this scrtipt for testing</p>
  
  <pre><code>&lt;?php
  
  ini_set('max_execution_time',1);
  set_time_limit(1);
  
  for($i=0;$i&lt;2;$i++) {
          echo time();
          echo '    i:' . $i;
          echo '&lt;br/&gt;';
          sleep(2);
  }
  phpinfo();
  </code></pre>
  
  <p>the php info outputs</p>
  
  <pre><code>Directive           Local Value  Master Value
  max_execution_time  1            30
  </code></pre>
  
  <p>but the script is not aborted after 1 sec. Why?</p>
