Comment(by danielk):

 bhuffman, it looks like VideoOutputXv::Show() is holding the X11 lock, and
 DrawUnusedRects() is waiting on it. Show() is only holding the lock for an
 XSync() which really shouldn't take any time at all when using XVideo or
 OpenGL rendering.

 I'm attaching a testing patch for you that will time how long this call is
 taking. If it's taking much longer than about 2 million cycles per frame
 this may be the source of the problem. Of course, this backtrace may just
 be a fluke.
