// **FIXME**: This seems to break occasionally on
// buildkite. For some reason the commit
// 3873745c8f6ffb45c990eb23b491d4b4b6182f95, which is on master
// (currently HEAD), is not found. It seems to load the history
// with d6880352fc7fda8f521ae9b7357668b17bb5bad5 as the HEAD.
//
// To temporarily fix this, we need to select "New Build" from the build kite
// build page that's failing.
// * Under "Message" put whatever you want.
// * Under "Branch" put in the branch you're working on.
// * Expand "Options" and select "clean checkout".
