title: Prevent django runserver from crashing or reload on save fix
body: <p>When I run <code>./manage.py runserver</code>, it often crashes because of mistakes I make, e.g. copy/paste code and save before modifying it or having a syntax error. Then I have to rerun the server.</p>
  
  <p>Is it possible to somehow have the server still running and then reload on my subsequent save so I don't have to run the server manually again?</p>
