    sleep, of if we've just woken up. From there, we can throw the relevant Sleep Event across

-   We should also consider holding a delay inhibitor in order to keep the system awake form long
-   enough to actually perform actions on the GoXLR. So when we see PrepareForSleep(true), perform
-   sleep actions then drop the inhibitor, and when we see PrepareForSleep(false), perform wake
-   actions and grab a new inhibitor. NOTE: The inhibitors used *SHOULD* be delay ones, the util
-   should not completely block sleeps from happening.
+   We also implement Sleep inhibitors so we can prevent the sleep from occurring until we've
+   confirmed that our sleep actions have been performed.
