In Michael's previous email, I understand that using PostMessage and
QueueAsyncCall will does the same thing.

How do I use Event to achieve the same? It seems that I can have N threads
"listen" to the same event, but cannot have the main thread to "listen" to
N different events?

Anyway, if I use Event I'll do some more reading of the document. For now,
I would like to know, performance-wise, which way is better? Using
QueueAsyncCall/PostMessage or RTLEvent*?
