It would be *a lot* of work to get all the iterators and adaptors to 
handle it. You would have to specialize each one of them. A lot of 
iterators do smart things like image->GetBufferPointer() and then work 
with the raw pointer for a while..  or return an address that's an 
indexed offset from the raw pointer. This will not work in your case, 
since the offset will be 8 times the correct offset.

Are you running out of memory ? Did you look to see if there were 
duplicates, for instance forcing filters to release their bulk data by 
using the ReleaseDataFlag etc
