title: Force drop a collection in MongoDB
body: <p>I can't delete a collection it's telling me <code>false</code> every single time..</p>
  
  <p>I do a <code>getCollections()</code> it gives me a lot of <code>tmp.mr.mapreduce_1299189206_1618_inc</code> (the ones I want to drop) I thought they were deleted during disconnection, but they're not (in my case).</p>
  
  <p>Then when I do: <code>db["tmp.mr.mapreduce_1299188705_5595"].drop()</code> I always get <code>false</code>  and it's not deleted.</p>
  
  <p>The logs are not really helpful:</p>
  
  <pre><code>Wed Mar  9 11:05:51 [conn4] CMD: drop customers.tmp.mr.mapreduce_1299188705_5595
  </code></pre>
  
  <p>Now I maxed up my namespaces and I cannot create more collections help?</p>
  
  <p>BTW, I can go down, this is not production (or even in production I can put it down too).</p>
