Description

At the moment, in many places we are not closing or manually invoking `.close()` over resources that could deal automatically with it through context managers. We should replace those manual usages of `.close()` with context managers in the documentation so that we get users used to go for the more robust solution that doesn't require dedicated exception handling and remembering to close things.
