[Container-tools] Issue with concurrent docker image pulls

[Lalatendu Mohanty]

Hi,

Couple of us seeing issue with docker image pulls in the CentOS 7 
Vagrant box. I spent some time and felt that its a bug in docker 1.6.2 
and found the issue [1] in docker github repo. It seems the issue is 
fixed in docker 1.7.1.

So wanted to throw this information to the list and see if others are 
also in agreement or have more information about it.

vagrant at localhost ~]$ docker --version
Docker version 1.6.2, build ba1f6c3/1.6.2

vagrant at localhost ~]$ sudo docker pull centos/httpd
