jQuery.globalEval(): Execution Delayed By Remote Scripts in Firefox

Description

This page demonstrates the issue. A remote script with a 5 second delay is inserted immediately before the call to globalEval(). In firefox <=3.6, the globalEval() script will not execute until the remote script is complete.

For Firefox 3.6, a work around exists. On the globalEval()'d script element, set the async property to true and embed the script text using data-uri. While it does not trigger synchronous execution, it does circumvent any delays caused by long polling remote scripts.

This is resolved in 1.6 as we're no longer using an injected script node.
