As Mike points out priority is of great importance from a browser point of  
view. Javascripts are executed in sequence on a page, and it is not  
uncommon for once script to load another one, or one style sheet to  
include another one. At the same time you have images from the main  
document being loaded. The relative importance of the resources can shift  
during the loading of the page as well, e.g. if the user started to scroll  
down the page and view new items.

We can see several use cases for Push, but there needs to be better user  
agent control.
