The .items, .keys, and .values methods in Python 2 make copies, so the
test framework uses the .iter* flavors of those methods. But in Python
3 those .iter* (and even the 2.7 .view*) flavors are removed and the
original methods return views.

Measurements were taken under Python2 to see what impact the copying
had, and there was none. Thus it is not worth the effort to avoid.

Reported as a compatibility issue by 2to3.
