Making a synchronous XmlHttpRequest can cause re-entrant behavior where an asynchronous image onload event is called during execution of a synchronous code block. It seems likely that this problem occurs for some other events as well.

Reproducible: Always

Steps to Reproduce:
1. set an image's src property in script.
2. make a synchronous XmlHttpRequest
Actual Results:  
The image onload will fire before the synchronous XmlHttpRequest returns.

Expected Results:  
The image onload fires after the synchronous XmlHttpRequest returns.
