contextmanager/ExitStack would likely help with the indentation
problem. As would simply breaking out some of the deeply nested code
into independent functions.

It may be that there's a problem worth addressing here, but I suggest
that you wait until you've had a chance to see if the existing
features in Python 3.5 resolve your issues before taking this
suggestion any further.
