is fairly straight forward. Once you get a little more complex you can run
the risk of piling up nested lock screen and then not having the visual
effect you desire when you unlock screen. I've found the easiest solution
is to:

if the lockScreen is false then lock screen

If you only ever use this then their will be no nested locked screens, so
you are only ever one command away from unlocking the screen.

if the lockScreen is true then unlock screen [with visual effect]

Then you don't have to bother about keeping track of pairs and can rest
easy at nights knowing that if left to the engine it only has to unlock
once when it goes idle - rather than having to wait a millisecond longer if
you had dozens of nested lock screen piled up.
