Thanks
I am OK on most part.
However, I think we had better do some basic check for below:
> //

If CreateEvent() fails, it does not make sense to call SetTimer().
Also CloseEvent (mDebuggerPrivate.BreakEvent); is called directly later.
So I suggest we add a Status check for CreateEvent. Also for NULL check in CloseEvent
Thank you
