Note that watching PrepareForShutdown(true)/PrepareForSleep(true) without taking a delay lock is racy and should not be done, as any code that an application might want to execute on this signal might not actually finish before the suspend/shutdown cycle is executed.

_Again_: if you watch PrepareForSuspend(true), then you really should have taken a delay lock first. PrepareForShutdown(false) may be subscribed to by applications which want to be notified about system resume events. _Again_: if you watch PrepareForShutdown(true)/PrepareForSleep(true), then you really should have taken a delay lock first.
