Good suggestions.  To handle the generic case, they could be added to 
ApplicationController; however, there are a few controllers that are 
handled a little differently (but only minor differences).

I had actually forgotten about rescue_from.  It also bypasses the filter 
chain, but we can still leverage something like execute_after_filters 
for such cases.
