                          When I check my power management assertions (MacBook Pro running macOS Sierra), I see the following line:

    $ sudo pmset -g assertions
    ...
    Idle sleep preventers: IODisplayWrangler

What is IODisplayWrangler and what does it mean that it is listed as an "idle sleep preventer"?
