Code review comment for lp://qastaging/~quequotion/slingshot/fix-1635776

I am rejecting this branch because we are accepting the simpler proposal (https://code.launchpad.net/~santileortiz/slingshot/fix-1635776/+merge/314255), which removes old hacky code that appears to be the source of the problem.

However, we've already reverted 1 commit that intended to fix this problem, so please stick around to make sure the problem is finally solved.
