 // A WaitableEvent can be a useful thread synchronization tool when you want to
 // allow one thread to wait for another thread to finish some work. For
 // non-Windows systems, this can only be used from within a single address
 // space.
 //
 // Use a WaitableEvent when you would otherwise use a Lock+ConditionVariable to
 // protect a simple boolean value.  However, if you find yourself using a
 // WaitableEvent in conjunction with a Lock to wait for a more complex state
