I wouldn't be so hasty.

First, you're basing it on a bad example.  Rebinding sys.stdout is bad
programming, period.  Wanting to save and restore it is even worse.
You might need this if you can't change the code you're calling, but
ordinarily, you should run away screaming from this kind of thing.
So, do you really want to go to -0 based on an example that really has
no business existing?

Second, that the "rebinding" statement should come before the "try:"
is *not* a subtlety.  It's the idiomatic way to do it, as familiar to
those who use it as the "while 1: break" idiom.
