Landed with the wrong bug number: https://hg.mozilla.org/integration/mozilla-inbound/rev/cace8e8e8556 so, backed out <https://hg.mozilla.org/integration/mozilla-inbound/rev/0ad4e00d7945> and relanded with the correct bug number: <https://hg.mozilla.org/integration/mozilla-inbound/rev/c00516696e8c>. Sorry for screwing this up!

FYI, to make your life easier if this happens again, you can just backout and re-land with DONTBUILD so you don't to worry about canceling all the pending builds.
