Tricky indeed... the TableRowIterator constructs the very list it is  
supposed to iterate over
--I mean: it creates the elements from another list instead of simply  
returning them un-"touched".
prefetchAll() is unused ATM, exactly because you would "touch" all  
rows (if I catch your intended meaning of that word correctly?)

OTOH, that method seems to have been added with auto-layout in mind  
anyway, so give it a shot, but mind the large tables...

Seems like, instead of simply prefetchNext(), you could try refining  
it to:

1) prefetchNext() [= get the row *group*, minor yet important detail]
2) doing what you need [= calculate content-length?]
3) immediately dispose of it

Another option would be to use an altered version of prefetchNext()
