Yeah, I was scratching my head on this one for a bit. :) I was  
getting an assert for a usage of a null RefPtr, but it wasn't  
happening at a predictable point in the code when tracing through  
with the debugger. "It's like it's in a different thread or  
something..." ..... light bulb illuminates :)

The amusing thing is that I had the exact same crash at basically the  
exact same point while running on the DC. How's that for consistency?

'Course that also led me to realize there's a race condition in the  
EventCollector, even with the mutex objects. That one's a tough nut  
to crack. We had a similar problem at work with DCOM callbacks  
happening after someone unregisters for them. I'll definitely take  
suggestions on that one if someone has an idea!
