title: PHP: "max execution time" immediately
body: <p>I am currently running a large website based on our own framework. When uploading a picture we occasionaly get a  <code>Maximum execution time of 30 seconds exceeded</code> within a fraction of a second. So I dont think the execution time is actually exceeded. </p>
  
  <p>Does anyone have a clue what might cause this?</p>
  
  <p>PHP version: 5.3.3</p>
