title: max_input_time= -1 What is the exact meaning of -1?
body: <p>I couldn't find this in the docs, but does:</p>
  
  <pre><code>max_input_time = -1
  </code></pre>
  
  <p>means there is no limit?</p>
  
  <p>I find it odd that <code>max_execution_time = 0</code> is forever.</p>
  
  <p>But what does <code>-1</code> mean for <code>max_input_time</code> ?</p>
