It's interesting to me that in VirtualDomainPageTest#setup, a Page  
instance is created, it's class_name set to VirtualDomainPage, and  
then it is reloaded as a VirtualDomainPage instance. Immediately  
afterward, @page.children.create is invoked, which doesn't blow up.

Looking closer, I found that the 'Anonymous module' that has 'no name  
to be referenced by' is NoCachePage, defined in the PageTestHelper.  
The stack and ruby-debug output is below. I confess that I don't know  
enough at the moment about all the interactions of your tests with  
the PageTestHelper, but this might help someone else, or you, figure  
out wazzup.
