I use this pattern for a lot of things, especially with GUI toolkits. 
For example :

- Raising a Click event outside of a MouseDown event handler.

- Reparenting a window after it has been closed, because GUI toolkits 
seems not to like reparenting directly in the Close event handler.

- Raise a "Modified" event once, and not for each modification during 
the same event loop.

...and so on.

It's funny that you don't understand the need, whereas you wrote the 
DocumentView class which uses this pattern constantly. Just search for 
the "Trigger" method applied on Timers. There are fourteen occurrences!
