title: Memory issues with HTTParty and download large files
body: <p>Is this going to cause memory issues with Ruby. I know Open-URI writes to a TempFile if the size goes over 10KB. But will HTTParty try and save the whole PDF to memory before it writes to TempFile?</p>
  
  <pre><code>src = Tempfile.new("file.pdf")
  src.binmode
  src.write HTTParty.get("large_file.pdf").parsed_response
  </code></pre>
