title: ansible sudo_user hangs for a few minutes and then fails (in a centos6.5.1 vagrant vm)
body: <p>I have these two simple tasks : </p>
  
  <pre><code>- name: I am 
    shell: "echo `id`"
  
  - name: say hello
    shell: echo "postgres saying hello"
    sudo_user: postgres
  </code></pre>
  
  <p>The second task fails after a long pause, the output is below
  (it's runing with vagrant with the verbose level vvv)
  (yes I have verified that the user postgres exists,
  I can do a sudo su postgres from inside the VM)</p>
