In EFL, we do the painting in the main loop, not in a thread, and r132392 seems to introduce an assumption that there is a second thread.
This infinite loop happens when loading e.g. http://trac.webkit.org/browser/trunk/Websites/webkit.org/blog-files/3d-transforms/poster-circle.html 

Bellow is a partial backtrace showing the problem:
