title: Simple way of turning off observers during rake task?
body: <p>I'm using restful_authentication in my app.  I'm creating a set of default users using a rake task, but every time I run the task an activation email is sent out because of the observer associated with my user model.  I'm setting the activation fields when I create the users, so no activation is necessary. </p>
  
  <p>Anyone know of an easy way to bypass observers while running a rake task so that no emails get sent out when I save the user?</p>
  
  <p>Thanks.</p>
