Buffered logs in Rails 3.2.1

I just upgraded my first application to Rails 3.2.1. It's been pretty
smooth which I appreciate. However I have noticed that my production
log is now buffered. It use to flush on every response but now it
does not. I would like to restore the previous behavior bug I have
not found any information on how to do so. If anyone knows how to do
this I would appreciate hearing it.

Thank you.
