Backed out since bug 773732 was backed out and this conflicted with it/relied on it: https://hg.mozilla.org/mozilla-central/rev/3b46b03dff5c
The backout had failures, so I have reverted it (effectively relanding this bug) and instead disabled bug 773732's test. Sorry for the noise here. https://hg.mozilla.org/mozilla-central/rev/618652af63c9
