> Refactor: Simplify WaitableEventWatcher.
> 
> This change uses a callback instead of a delegate for specifying what
> should be called when a WaitableEvent occurs.
> 
> This simplifies the class and gets rid of a workaround internal to the
> class to prevent name collision on "Delegate" inner classes.
