I generally prefer a pull model because it means I don't have to resort 
to tricks to get and keep my state around.

I think the pull model falls apart when you want to do several things in 
parallel as data comes streaming in -- e.g., build a DOM tree, 
canonicalize the data for hashing (and XML DSIG).  You then run into the 
old GUI limitation of event loops:  "there can be only one."
