title: django eggs template Loader error
body: <p>I'm trying to install <code>dajax</code>/<code>dajaxice</code> according to their documentation, which suggests that I uncomment the eggs template loader (third in tuple below below) in my <code>settings.py</code>.</p>
  
  <pre><code>TEMPLATE_LOADERS = (
      'django.template.loaders.filesystem.Loader',
      'django.template.loaders.app_directories.Loader',
      'django.template.loaders.eggs.Loader',
  )
  </code></pre>
  
  <p>However, this makes my site stop working with an "IOError at /: sys.stdin access restricted by mod_wsgi" on my development machine.  When I look at where the error arises, it arises in python eggs that are unconnected to this project (I'm not using virtualenv which may be able to help) (or even django) and disappears when I comment out the line again.  (The template its looking for is easily found in the <code>TEMPLATES_DIR</code> when the eggs loader is commented out).</p>
  
  <p>The traceback is:</p>

  <p>My question is there anyway to enable the eggs template loader but only check through eggs of <code>INSTALLED_APPS</code>?  I'd rather not have to switch to virtualenv.  Also these eggs appear in my python path:</p>
