DRYer use of Logger#silence in ActionController: +1's needed

Hello,

I saw the the code for silencing the logger for the duration of a
block is duplicated both in Logger (where it SHOULD be, IMHO) and in
ActionController. This patch fixes it:

http://dev.rubyonrails.org/ticket/10613

Note my question there regarding other logging systems that might
break. How can we deal with that?

Thanks,
