That's helpful, but not entirely accurate.  I encountered this problem 
in development mode when an extension that uses alias_method_chain gets 
reloaded but its previous amc was not removed from the class.  Thus you 
get it aliasing the method over and over.  In most cases I was able to 
run in production mode locally, which removed the problem.
