This patch begs the question why we are passing iterators by value at
all. Looking at the code generated for all of these little structures
we see huge numbers of structure copies that aren't being eliminated
even when the iterator functions get inlined.
I have a patch pending which makes the iterators smaller and exclusively
passes the address around.
