title: django 1.4 Many-to-Many bulk add
body: <p>I was wondering if there is the equivalent of a "add all" or "bulk create" for many to many relationships which reduce the number of queries (I will be doing this for a long list)?</p>
  
  <p>The docs on this subject seem to suggest that this is not possible:</p>

  <pre><code>**Associate the Article with a Publication:**
  a1.publications.add(p1)
  
  **Create another Article, and set it to appear in both Publications:**
  a2 = Article(headline='NASA uses Python')
  a2.save()
  a2.publications.add(p1, p2)
  a2.publications.add(p3)
  </code></pre>
