Thanks for the hint, folks.

I'm not a zope newbie, and this still bit me.  IMO there's something
fairly wrong with the current setup.  either the default behaviour
should be changed to orphans=0, or the visibility of default values
for tags should be improved (from the book: "orphan=int The desired
minimum batch size" - no mention of defaults).

Furthermore, the 'feature' doesn't work as I'd expect.  In the example
I posted, for the sequence (1,2,3,4), I got: 

 batch 1: 1
 batch 2: 2 3 4
 batch 3: 3 4
 batch 4: 4

This isn't in batches of at least 3... If it were iterating in minimum
batches of 3, shouldn't that be: 

 batch 1: 1 2 3
 batch 2: 2 3 4
 batch 3: 2 3 4
 batch 4: 2 3 4

It's ugly!
