title: What is StatReloader while running Django?
body: <p>I've just created new Python 3.7 virtualenv with Django 2.2</p>
  
  <p>And each <code>runserver</code> it prints:</p>
  
  <blockquote>
    <p>Watching for file changes with StatReloader</p>
  </blockquote>
  
  <p>I could not find any info in Django's docs etc.</p>
  
  <p>Is it related specially to Django somehow?
  Does it go with Django?
  What it does?
  Why is it printed in red in PyCharm?
  Should I be careful about something?
  Could it be disabled?</p>
  
  <p>Big thx</p>
