title: Django database hung in migration
body: <p><strong>EDIT: I solved the issue.  The problem was that I had a shell open with a database connection to that model.  I exited the shell, and everything continued.</strong></p>
  
  <p>I just migrated my database with south, but rather than migrating one app, i accidentally migrated the whole project (<code>./manage.py migrate</code>). Everything went fine until it got to the app that needed the migration.  I didnt get an error, but it is hung at that point:</p>
  
  <pre><code>~/django/baeren $ ./manage.py migrate
  Running migrations for home:
  - Nothing to migrate.
   - Loading initial data for home.
  Installed 0 object(s) from 0 fixture(s)
  Running migrations for price:
  - Nothing to migrate.
   - Loading initial data for price.
  Installed 0 object(s) from 0 fixture(s)
  Running migrations for gallery:
  - Nothing to migrate.
   - Loading initial data for gallery.
  Installed 0 object(s) from 0 fixture(s)
  Running migrations for menu:
   - Migrating forwards to 0006_auto__add_field_menu_category.
   &gt; menu:0006_auto__add_field_menu_category
  </code></pre>
  
  <p>The site is still running, and everything is accessible on the admin page except for that specific model.  Is it ok to just kill the process and remigrate, or would I be risking something unrecoverable that I don't understand?  If the latter, is there an alternative route?</p>
