Comment 5 for bug 1370185

More info that may help with fix coverage, I run the 3 stack-create calls as described and got the result below on my devstack.
This devstack runs only a standalone heat and my template includes an inner heat::Stack resource. the resources are successfully created on a remote region full devstack installation.

I guess standalone should not make any different that let the 3 stacks be successfully created instead of staying in progress.
