title: Text file busy @ unlink_internal
body: <p>I'm having an issue with refile and vagrant using synced folders. The issue is that whenever i try to save a file the following error occurs:</p>
  
  <p>Errno::ETXTBSY (Text file busy @ unlink_internal - /vagrant/vidya/tmp/uploads/ca
  che/2dcd0c3fd391985ffe88ea30d826890c817fe64756f5fb6c92408368caa0):</p>
  
  <p>Here's the full stack trace <a href="http://pastebin.com/TaUn9eJW" rel="nofollow">http://pastebin.com/TaUn9eJW</a></p>
  
  <p>This however works in the vagrant guest if it isnt within the synced folders. I used carrierwave to test if it would fail as well, it however didn't and carrierwave works fine with synced folders.</p>
  
  <p>Is there anything that refile and or rails does that keeps that file busy?</p>
