title: EBUSY on unlink from "npm install -g oauthd"
body: <p>So, I have an open issue at the oauthd repo: <a href="https://github.com/oauth-io/oauthd/issues/126" rel="nofollow">Issue</a> but the activity in their issue list looks very sporadic.</p>
  
  <p>I'm trying to execute "npm install -g oauthd" from a MINGW32 shell.<br>
  I'm being told by the console that I am doing that wrong.</p>
  
  <pre><code>abates@MACHINE /c/dev/tools
  $ npm -v
  1.4.28
  
  abates@MACHINE  /c/dev/tools
  $ npm install -g oauthd

  <p>I couldn't find any useful information about the "EBUSY, unlink..." error that seems to have triggered the crash. </p>
