title: load a pickle file from a zipfile
body: <p>For some reason I cannot get cPickle.load to work on the file-type object returned by ZipFile.open().
  If I call read() on the file-type object returned by ZipFile.open() I can use cPickle.loads though.</p>
  
  <p>Example ....</p>
  
  <pre><code>import zipfile
  import cPickle
  
  # the data we want to store
  some_data = {1: 'one', 2: 'two', 3: 'three'}
  
  #
  # create a zipped pickle file
  #
  zf = zipfile.ZipFile('zipped_pickle.zip', 'w', zipfile.ZIP_DEFLATED)
  zf.writestr('data.pkl', cPickle.dumps(some_data))
  zf.close()
  
  #
  # cPickle.loads works
  #
  zf = zipfile.ZipFile('zipped_pickle.zip', 'r')
  sd1 = cPickle.loads(zf.open('data.pkl').read())
  zf.close()
  
  #
  # cPickle.load doesn't work
  #
  zf = zipfile.ZipFile('zipped_pickle.zip', 'r')
  sd2 = cPickle.load(zf.open('data.pkl'))
  zf.close()
  </code></pre>
  
  <p>Note: I don't want to zip just the pickle file but many files of other types.  This is just an example.</p>
