Thank you for clarifying.  That did puzzle me a bit and I thought that I 
simply misunderstood the Push process.

What I see in Developer Tools is that the resources that I reference in 
the "Link" header are downloaded first, and are downloaded faster.  The 
"Initiator" of those resources shows as "Other", as opposed to most 
other resources who show something like a URI.

Understood.  I am only "pushing" (I guess not a real push, but a 
suggestion to the browser via the "Link" header) links to a few 
resources that are required for loading and rendering the page, like the 
stylesheet, javascript, and image sprite.
