One thing you need to keep in mind is that dtml-in has an orphan
attribute that determines the minimum amount of items to print out.  If
orphan is set to 3 (default) and you have a list of 6 items, and you set
size=4, the dtml-in tag will realize that 2 is too little to have on one
page and so it displays all 6.

If you don't want this, set orphan=0 in the dtml-in.
