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

[serverherder]

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.

#4545 is a duplicate of this ticket.

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