Fill this in...

The original motivation for this is in this blog post: http://marc-abramowitz.com/archives/2013/07/19/python-context-manager-for-redirected-stdout-and-stderr/

There is some long and confusing background in http://bugs.python.org/issue15805 — where that started out as a very simple context manager that doesn't deal with subprocesses, then folks suggested a whole bunch of more complex stuff, and then they ultimately decided to go back to doing something super simple and suggested that other more advanced stuff go in a separate issue.

TL;DR is that issue15805 is going to be something simple and more for beginners but they're open to doing something fancier with subprocesses in a separate issue that I think is yet to be filed...
