Personally I would suggest bump the Priority level of this meta tracker ticket a little bit higher as it has BIG impact for large sites. Just my 2 cents.

Also is it possible that we could try to fix it in 1.9.1 instead of 2.0? Just a thought..

Should this meta issue reference ~~MDL-18468~~? In other words, are restore problems being gathered here as well? having ~~MDL-12594~~ as a dependency seems to imply so....
