observers should not add an after_find method to the observed class

Reported by Stefan Kaes | July 15th, 2008 @ 07:16 PM | in 2.1.1

Observers should not modify observed classes by defining an empty after_find method on the observed class.

First, it's evil to silently add a method.

Second, it slows down instantiating objects of the observed class, because executing the callback chain is expensive. I measure 10-20% difference for my application.
