title: Cucumber After hook is being executed before scenario ends
body: <p>I have an After hook in hooks.rb that deletes users created in the last scenario.
  I started to notice that when tests run <em>at a specific time of the day</em>, this hook is being executed <em>in the middle of a scenario</em>. 
  There is a method that executes until a certain line and then the hook executes just before an assert command in that method, which fails because of it.
  The tests are run from a batch file ("ruby file_name.rb").</p>
  
  <p>Does anyone have an idea why this might happen or how to solve it?</p>
  
  <p>Thanks!</p>
