title: No ConcurrentList<T> in .Net 4.0?
body: <p>I was thrilled to see the new <code>System.Collections.Concurrent</code> namespace in .Net 4.0, quite nice!  I've seen <code>ConcurrentDictionary</code>, <code>ConcurrentQueue</code>, <code>ConcurrentStack</code>, <code>ConcurrentBag</code> and <code>BlockingCollection</code>.</p>
  
  <p>One thing that seems to be mysteriously missing is a <code>ConcurrentList&lt;T&gt;</code>.  Do I have to write that myself (or get it off the web :) )? </p>
  
  <p>Am I missing something obvious here?</p>
