Hi,

I know of two exceptions. (If this didn't change since last time I look). Both 
bugs and answers notifications look at the snapshot of the messages collection 
to see if a new message was added. This is to make decisions about the 
notifications.

So at least the messages collection on Bug and Question should be snapshoted 
unless we change the way this notification code was changed.
