Python 3.2 has this lovely new contextlib.ContextDecorator mixin [1]
for context manager classes that allows you to apply the context
manager as a decorator. The docs for this feature include the note:
ContextDecorator is used by contextmanager(), so you get this
functionality automatically.

Hi,
I'm getting the following error and I can't Google my way out of it:
close failed in file object destructor:

lost sys.stderr
My python file is simple print "test". I run it, it works no problem.
I pipe the output to a file "run > logfile" and that's the error I
get.
