defer_javascript should turn off for requests with header XMLHttpRequest #480

Description

From amattie@gmail.com:


I think defer_javascript should automatically disable when the request contains 
a "X-Requested-With: XMLHttpRequest" header or a "Origin" header w/ any value. 
The reasoning is that any content placed on the page by XmlHttpRequest will 
have the expectation that the script will run as soon as it's on the page; in 
the current implementation, those script tags don't appear to run at all.

Like I said earlier, defer_javascript looks very promising and we're excited to 
eventually be able to use it. It appears to speed up rendering significantly; I 
wouldn't have bothered with investigating issues otherwise!
